Choke Pulloff

Inspect/Test/Replace

A malfunctioning choke can cause a variety of performance problems, from no-start to missing and power loss at cruising speeds. These problems can be caused by the choke being stuck closed, the choke being stuck open, inoperative choke pull-off, or a malfunctioning bimetal choke coil.

A visual inspection may identify the trouble spot quickly. Remove the air cleaner, making sure to label each vacuum hose as it is disconnected. If the engine is cold, the choke should be closed. Watch the choke plate as an assistant cranks the engine.

  • Check for broken or leaking vacuum hoses.
  • Check for a cracked housing.
