Carburetor
If engine idle speed is too high the vehicle will creep. If idle speed is too low the engine will
stall. To adjust idle speed, do the following:
1. Lock the parking brake.
2. Start the engine.
3. Allow the engine to warm up for approximately five minutes.
4. Adjust the carburetor idle screw either in or out until the desired idle speed is reached.
Turning the screw in (clockwise) will increase idle speed. Turning the screw out (coun-
ter-clockwise) will decrease idle speed.
Tip: If using an RPM gauge, the factory idle speed setting for 90cc models is 1700 +/- 100 RPM.
