Adjusting the Carburetor
Procedure Perform the procedure below to adjust the carburetor.
1.
Start the engine and allow it to warm up to operating temperature.
2.
Set the pilot screw (a) two turns out. See Note.
3.
With the engine idling, turn the pilot screw (a) in or out to the setting that
produces the highest rpm.
4.
After the pilot screw is adjusted, turn the throttle stop screw (b) to obtain the
standard idle speed. See Technical Data.
Note: On some engines the pilot screw is fitted with a limiter cap (c) to prevent
excessive enrichment of the air-fuel mixture in order to comply with emission
regulations. The mixture is set at the factory and no adjustment should be
necessary. Do not attempt to remove the limiter cap. The limiter cap cannot be
removed without breaking the pilot screw.
