FLUID LEVEL CHECK 230 Models
Up to 1976 models, use ATF in the carburetor damper. Beginning with 1977 models, use ATF in the winter and engine oil in the summer.
Some carburetor models use an oil reservoir and some do not. If no reservoir is used, unscrew and remove the damper. The oil level should be at the upper edge of the piston pin. If a reservoir is used, the oil level should be as specified (see illustration).
