Efficient carburetion depends greatly on careful cleaning and inspection during overhaul, since dirt, gum, water, or varnish in or on the carburetor parts are often responsible for poor performance.

Overhaul your carburetor in a clean, dust-free area. Carefully disassemble the carburetor, referring often to the exploded views. Keep all similar and look-alike parts segregated during disassembly and cleaning to avoid accidental interchange during assembly. Make a note of all jet sizes.

When the carburetor is disassembled, wash all parts (except diaphragms, electric choke units, pump plunger, and any other plastic, leather, fiber or rubber parts) in clean carburetor solvent. Do not leave parts in the solvent any longer than is necessary to sufficiently loosen the deposits. Excessive cleaning may remove the special finish from the float bowl and choke valve bodies, leaving these parts unfit for service. Rinse all parts in clean solvent and blow them dry with compressed air or allow them to air dry. Wipe clean all cork, plastic, leather and fiber parts with a clean, lint-free cloth.

Blow out all passages and jets with compressed air and be sure that there are not restrictions or blockages. Never use wire or similar tools to clean jets, fuel passages, or air bleeds. Clean all jets and valves separately to avoid accidental interchange.

Check all parts for wear or damage. If wear or damage is found, replace the defective parts. Especially check the following:

  1. Check the float needle and seat for wear. If wear is found, replace the complete assembly.
  2.  
  3. Check the float hinge pin for wear and the float(s) for dents or distortion. Replace the float if fuel has leaked into it.
  4.  
  5. Check the throttle and choke shaft bores for wear or an out-of-round condition. Damage or wear to the throttle arm, shaft, or shaft bore will often require replacement of the throttle body. These parts require a close tolerance of fit; wear may allow air leakage, which could affect starting and idling.
  6.  

Throttle shafts and bushings are not included in overhaul kits. They can be purchased separately.

  1. Inspect the idle mixture adjusting needles for burrs or grooves. Any such condition requires replacement of the needle, since you will not be able to obtain a satisfactory idle.
  2.  
  3. Test the accelerator pump check valves. They should pass air one way but not the other. Test for proper seating by blowing and sucking on the valve. Replace the valve if necessary. If the valve is satisfactory, wash the valve again to remove breath moisture.
  4.  
  5. Check the bowl cover for warped surfaces with a straightedge.
  6.  
  7. Closely inspect the valves and seats for wear and damage, replacing as necessary.
  8.  
  9. After the carburetor is assembled, check the choke valve for freedom of operation.
  10.  

Carburetor overhaul kits are recommended for each overhaul. These kits contain all gaskets and new parts to replace those that deteriorate most rapidly. Failure to replace all parts supplied with the kit (especially gaskets) can result in poor performance later.

Carburetor manufacturers supply overhaul kits of three basic types: minor repair; major repair; and gasket kits. Basically, they contain the following:

Minor Repair Kits



All gaskets
 
Float needle valve
 
Volume control screw
 
All diaphragms
 
Spring for the pump diaphragm
 

Major Repair Kits


All jets and gaskets
 
All diaphragms
 
Float needle valve
 
Volume control screw
 
Pump ball valve
 
Main jet carrier
 
Float
 
Complete intermediate rod
 
Intermediate pump lever
 
Complete injector tube
 
Some cover hold-down screws and washers
 

Gasket Kits


All gaskets
 

After cleaning and checking all components, reassemble the carburetor, using new parts and referring to the exploded view. When reassembling, make sure that all screws and jets are tight in their seats, but do not overtighten, as the tips will be distorted. Tighten all screws gradually, in rotation. Do not tighten needle valves into their seats; uneven jetting will result. Always use new gaskets. Be sure to adjust the float level when reassembling.

FLOAT AND FUEL LEVEL ADJUSTMENT 4-134 Carter Model YF Carburetor



  1. Remove and invert the bowl cover.
  2.  
  3. Remove the bowl cover gasket.
  4.  
  5. Allow the weight of the float to rest on the needle and spring. Be sure that there is no compression of the spring other than by the weight of the float.
  6.  
  7. Adjust the level by bending the float arm lip that contacts the needle (not the arm) to provide 17 / 64 in. of clearance on models made during and after 1968. On models prior to 1968, the clearance is to be set at 5 / 16 in.

Fig. Fig. 23: Adjusting the float drop Rochester 2GV, 6 Cyl-225 engine and 8 Cyl-350 engine

The procedure for adjusting the float level of the two-barrel carburetor installed on the 6-225 is the same as the procedure for the 4-134 up to Step 4.

The actual measurement is taken from the air horn gasket to the lip at the toe of the float. This distance should be 15 / 32 in. To adjust the float level, bend the float arm as required.

The float drop adjustment is accomplished in the following manner: With the bowl cover turned in the upright position, measure the distance from the gasket to the notch at the toe of the float. Bend the tang as required to obtain a measurement of 1 7 / 32 in.

6-226 Carter Model YF Carburetor

  1. Remove and invert the bowl cover.
  2.  
  3. Remove the bowl cover gasket.
  4.  
  5. Allow the weight of the float to rest on the needle and spring. Be sure that there is no compression of the spring other than by the weight of the float.
  6.  
  7. Adjust the level by bending the float arm lip that contacts the needle (not the arm) to provide 9 / 32 in. of clearance.
  8.  

6-230 Holley 1920 Carburetor

  1. Remove the carburetor.
  2.  
  3. Slide float gauge J-10238 into position at the economizer body baffle and check the setting. The float should just touch the gauge.
  4.  
  5. If necessary, bend the float tab with needle nosed pliers. Do not allow the float tab to contact the float needle during this operation. Recheck the setting.
  6.  
  7. Slide the economizer diaphragm into position, making sure that the vacuum holes are aligned and that the stem is on the power valve.
  8.  
  9. Install and tighten the cover screws.

Fig. Fig. 25: Adjusting the float level Carter RBS carburetor

With the carburetor inverted, remove the 4 screws which secure the fuel bowl to the fuel bowl flange on the carburetor body. Remove the fuel bowl gasket. With only the weight of the float pressing the intake valve needle into the seat, measure the clearance between the fuel bowl flange of the carburetor body and each end of the float. This clearance should be 21 / 32 in. If necessary, bend the lip of the float which touches the intake valve needle to obtain the correct clearance. Take care not to press the needle into the seat. Install the fuel bowl gasket on the fuel bowl flange, then install the fuel bowl.

6-232 1970-72, 6-258 1971-76 Carter YF Carburetor

  1. Remove and invert the air horn assembly and remove the gasket.
  2.  
  3. Measure the distance between the top of the float at the free end, and the air horn casting. The measurement should be 29 / 64 in. Adjust by bending the float lever.
  4.  

The fuel inlet needle must be held off its seat while bending the float lever in order to prevent damage to the needle and seat.

  1. To adjust the float drop, hold the air horn in the upright position and measure the distance between the top of the float, at the extreme outer end, and the air horn casting. The measurement should be 1 1 / 4 in. Adjust by bending the tab at the rear of the float lever.
  2.

  2.  
  3. Apply light finger pressure to the vertical float tab to exert GENTLE pressure against the inlet needle.
  4.  
  5. Lay a straightedge across the float bowl and measure the gap between the straightedge and the top of the float at its highest point. The gap should be 1 / 4 inch.
  6.  
  7. If adjustment is necessary, remove the float and bend the lower tab. Replace the float and check the gap.
  8.  

8-304, 8-360 Autolite Model 2100, 2150 Carburetor

With the air horn assembly and the gasket removed, raise the float by pressing down on the float tab until the fuel inlet needle is lightly seated. Using a T-scale, measure the distance from the fuel bowl machined surface to either corner of the float at the free end. The measurement should be 3 / 8 inch for 1966-75 models and 15 / 16 inch for 1976-79 models. To adjust, bend the float tab and hold the fuel inlet needle off its seat in order to prevent damage to the seat and the tip of the needle.

Invert the air horn assembly and remove the gasket. Use a T-scale to measure the distance from the float pontoons to the air horn casting. Position the horizontal scale over the flat surface of both float pontoons at the free ends and parallel to the air horn casting. Hold the lower end of the vertical scale in full contact with the smooth area of the air horn casting, located midway between the main discharge nozzles.

For more precise float level determination, see the accompanying illustrations for making a tool to measure and set the float level.

Do not allow the end of the vertical scale to come in contact with any gasket sealing ridge while measuring the float setting.

The free end of each float pontoon should just touch the horizontal scale. If one pontoon is lower than the other, twist the float and lever assembly slightly to align them. The measurement would be 13 / 16 in.

Adjust the float level by bending the tab which contacts the fuel inlet needle.

8-360, 8-401 Motorcraft 4350 Carburetor

  1. Invert the air horn assembly and remove the gasket.
  2.  
  3. Measure the distance from the floats to the air horn rim using a T-scale. Position the horizontal scale over the flat surface of both floats at the free ends, parallel to the air horn casting. Hold the lower end of the vertical scale in full contact with the smooth area of the casting, midway between the main discharge nozzles.
  4.  

For more precise float level determination, see the accompanying illustrations for making a tool to measure and set the float level.

Do not allow the end of the vertical scale to contact any gasket sealing ridge while measuring the float setting.

  1. The free end of the floats should just touch the horizontal scale. Float-to-air horn casting distance should be 29 / 64 inch. Bend the vertical tab on the float arm to adjust the distance.
  2.  

8-327 Holley Model 2209 (2-bbl) Carburetor

With the air horn of the carburetor removed from the main body, invert the air horn with the float assembly attached and measure the distance between the float and the air horn. The distance should be 9 / 16 in. Adjust the distance by bending the tab at the float hinge.

To adjust the float drop, turn the air horn right side up and let the float hang down freely. The bottom surface of the float should be parallel with the gasket mating surface of the air horn. Adjust the position of the float by bending the float drop tang.

8-327 Holley Model 4160 (4-bbl) Carburetor

To perform a preliminary dry float adjustment on both the primary and secondary fuel bowl float assemblies, invert the fuel bowl and let the float rest on the fuel inlet valve and seat assembly. The fuel inlet valve and seat assembly can be rotated until the float is parallel with the fuel bowl floor (actually the top of the fuel bowl chamber inverted). Note that this is an initial dry float setting which must be rechecked with the carburetor assembled and on the engine to obtain the proper wet fuel level.

This carburetor has an externally adjustable needle and seat assembly that allows the fuel level to be checked and adjusted without removing the carburetor from the engine.

With the engine running, remove the sight plug from the carburetor bowl on the side opposite from the fuel inlet. If the fuel level is too high, excess fuel will run out through the sight hole. The correct fuel level is just up to the threads at the bottom of the sight hole.

To adjust the level, loosen the top lockscrew on the needle and seat assembly and adjust with the lower nut until the float maintains the fuel at the correct level. Tighten the top lockscrew without disturbing the adjusting nut.

The above procedure applies to both the primary and secondary fuel bowls.

8-350 Rochester Model 2GV (2-bbl) Carburetor

The float level and float drop on the Rochester Model 2GV is adjusted in the same manner as for the Model 2G installed on the 6-225 engine. Refer to the procedure given for that engine. The float level measurement is the same for both carburetors. The float drop measurement for the Model 2GV on the 8-350 is 1 3 / 4 in.

FAST IDLE ADJUSTMENT (AIR CLEANER OFF)4-134 Engine



With the choke held in the wide open position, the lip on the fast-idle rod should contact the boss on the body casting. Adjust it by bending the fast idle link at the offset in the link.

6-225 Engine

No fast idle speed adjustment is required. Fast idle is controlled by the curb idle speed adjustment screw. If the curb idle speed is set correctly and the choke rod is properly adjusted, fast idle speed will be correct.

6-226 Engine

With the choke held in the wide open position, the lip on the fast-idle rod should contact the boss on the body casting. Adjust it by bending the fast idle link at the offset in the link.

6-230 Engine See Figure 29

Click image to see an enlarged view

Fig. Fig. 29: Fast idle cam index setting Carter RBS carburetor

  1. Connect a tachometer according to the manufacturer's instructions.
  2.  
  3. On vehicles equipped with a manual choke, adjust the choke wire to give maximum operation of the choke valve. With the engine off the choke fully open, adjust the fast idle screw to obtain a 0.030 in. gap between the end of the screw and the cam.
  4.  
  5. On vehicles equipped with an automatic choke, run the engine to normal operating temperature. With the choke valve fully open and the engine idling in neutral, open the throttle slightly and rotate the fast idle cam until the fast idle screw contacts the second step of the fast idle cam. Release the throttle. The linkage pullback spring will cause the fast idle adjusting screw to hold the cam in this position. The tachometer should read 2,100 rpm. If not, turn the adjusting screw until it does.
  6.  

1966-69 6-232 Engine

Fast idle adjustment should only be made when the carburetor is removed from the engine. With the carburetor body inverted, rotate the fast idle cam and fast idle weight to the extreme counterclockwise position. The cam should press against the fast idle prong of the throttle shaft and lever assembly to hold the throttle valve slightly open. Bend this prong, if necessary, to obtain 0.023 in. of clearance between the throttle valve plate and the idle port side of the carburetor bore, with the cam in this position. With the choke valve closed tightly and the fast idle connector rod at the end of the slot in the fast idle weight, bend the offset portion of the connector rod to align the index mark of the cam with the fast idle prong of the throttle shaft and lever assembly.

1970-72 6-232 and 1971-76 6-258 Engines

Partially open the throttle and close the choke valve to rotate the fast idle cam into the cold start position. While holding the choke valve closed, release the throttle. With the fast idle cam in this position, the fast idle adjusting screw must be aligned with the index mark at the back side of the cam. Adjust by bending the choke rod at its upper angle.

1977 and Later 6-258 Engines with Carter BBD Carburetors

  1. Loosen the choke housing cover and turn it 1 / 4 turn right. Tighten one screw.
  2.  
  3. Slightly open the throttle and place the fast idle screw on the second cam step.
  4.  
  5. Measure the distance between the choke plate and the air horn wall. The gap should be 3 / 32 inch.
  6.  
  7. If adjustment is necessary, bend the fast idle cam link down to increase measurement or up to decrease it.
  8.  
  9. Loosen the choke cover screw and return the cap to its original setting. Tighten the cover screws.
  10.  

8-350 Engines

No fast idle speed adjustment is required. Fast idle is controlled by the curb idle speed adjustment screw. If the curb idle speed is set correctly and the choke rod is properly adjusted, fast idle speed will be correct.

8-304, 8-360 and 8-401 Engines with 2-bbl Carburetors See Figure 30

Fig. Fig. 30: Fast idle cam index setting Autolite (Motorcraft) 2100 carburetor

Set the fast idle speed with the engine at operating temperature and the fast idle speed adjusting screw against the index mark (second step) of the fast idle cam. Adjust by turning the fast idle speed adjusting screw until 1,600 rpm is attained.

8-360 and 8-401 Engines with 4-bbl Carburetors

  1. Run the engine to normal operating temperature. Connect an accurate tachometer to the engine.
  2.  
  3. Disconnect and plug the EGR and TCS vacuum lines.
  4.  
  5. Position the fast idle screw against the first step of the fast idle cam. Adjust the fast idle screw to give a reading of 1,600 rpm.
  6.  
  7. Return the linkage to its normal position, unplug and reconnect the vacuum lines.
  8.  

8-327 Engines with 2-bbl Carburetors

With the throttle stopped on the high step of the fast idle cam, the fast idle speed should be 1,800 rpm with the engine at normal operating temperature. Adjust the fast idle speed by bending the tab on the throttle lever.

8-327 Engines with 4-bbl Carburetors

The preliminary fast idle setting with the carburetor removed from the engine is made by turning the fast idle adjusting screw to obtain 0.025 in. clearance between the throttle valve and carburetor bore opposite the idle port, with the fast idle adjusting screw on the high step of the cam.

The fast idle setting can be altered with the carburetor on the car to suit individual requirements. However, it has been found that the aforementioned bench setting is most desirable for the best overall performance. The fast idle setting with the adjusting screw on the high step of the cam and the engine at normal operating temperature is about 1,700 rpm.

CHOKE LINKAGE ADJUSTMENT Engines With a Manual Choke



The choke is manually operated by a cable that runs from the dash mounted control pull knob to the set screw on the choke actuating arm. To adjust the choke, loosen the set screw at the choke actuating lever and push in the dash knob as far as it will go. Open the choke plate as far as it will go and hold it with your finger while the set screw is tightened.

Engines with an Automatic Choke See Figure 31

Click image to see an enlarged view

Fig. Fig. 31: Choke unloader adjustment Rochester 2GV carburetor 6 Cyl-225 engine and 8 Cyl-350 engine

The automatic choke setting is made by loosening the choke cover retaining screws and rotating the cover to align the notch on the cap with the proper index mark on the casting. See the carburetor specifications chart at the beginning of this chapter for the proper setting.

CHOKE UNLOADER ADJUSTMENT All Engines with Automatic Choke Mechanisms



With the throttle held fully open, apply light pressure on the choke valve toward the closed position and measure the clearance between the edge of the choke valve and the air horn wall. On all 1962-69 engines, the measurement is taken at the upper edge of the choke plate. On 1970 and later engines, the measurement is taken at the lower edge of the choke plate. Adjust the distance by bending the tang on the throttle lever which contacts the fast idle cam. Bend toward the cam to decrease the clearance. See the carburetor specifications chart at the beginning of this section for the proper gap.

Do not bend the unloader downward from a horizontal position (1970 and later engines). After making the adjustment, make sure that the unloader tang does not contact the main body flange when the throttle is fully open. Final unloader adjustment must always be done on the vehicle. The throttle should be fully opened by depressing the accelerator pedal to the floor. This is to assure that full throttle is obtained.

DASHPOT ADJUSTMENT Except the 4-134 and 6-225



With the throttle set a curb idle position, fully depress the dashpot stem and measure the clearance between the stem and the throttle lever. Adjust the clearance by loosening the locknut and turning the dashpot.

4-134 and 6-225 Engines See Figures 32 and 33

Fig. Fig. 33: Choke rod adjustment Rochester 2GV carburetor

The dashpot adjustment is made with the throttle set at curb idle. Loosen the dashpot locknut and turn the dashpot assembly until the dashpot plunger contacts the throttle lever without the plunger being depressed. Then turn the dashpot assembly 2 1 / 2 turns against the throttle lever, depressing the dashpot plunger. Tighten the locknut securely.

INITIAL CHOKE VALVE CLEARANCE ADJUSTMENTAll Except 6-230 Engines



  1. Position the fast idle screw on the top step of the fast idle cam.
  2.  
  3. Using a vacuum pump, seat the choke vacuum break.
  4.  
  5. Apply a light closing pressure on the choke plate to position the plate as far closed as possible without forcing it.
  6.  
  7. Measure the distance between the air horn wall and the choke plate. If it is not that specified in the carburetor specifications charts, bend the choke vacuum break link until it is.
  8.  

GOVERNOR ADJUSTMENT



  1. Connect a tachometer to the engine. Adjust the carburetor to obtain a smooth idle at 600 rpm. Shut OFF the engine.
  2.  
  3. Check the throttle linkage to be sure that the throttle plate can be set at the wide open position. Make sure that the throttle and governor linkage are operating freely.
  4.  
  5. Place the carburetor in the wide open throttle position and pull the governor handle all the way out.
  6.  
  7. Adjust the governor-to-bell crank rod so that the linkage will hold the carburetor in the wide open throttle position.
  8.  
  9. Close the governor control and start the engine.
  10.  
  11. Pull the governor control out to the last notch and adjust the cable length at the adjusting yoke so that the engine will run at 2,600 rpm.
  12.  
  13. Close the governor control and make sure that the engine returns to the 600 rpm idle speed. Check that the linkage operates freely. If the engine does not return to the 600 rpm figure, loosen the locknut, at the dashpanel, which retains the governor hand control to the rod and back off the handle until the idle speed adjusting screw rests on the stop. Tighten the locknut.
