5.10 Adjusting 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.

5.11 Adjusting the Idle Speed

To adjust idle speed:

1. Start engine and allow it to warm up to normal operating temperature.

2. Turn throttle stop screw (b) in to increase speed, out to decrease speed.
