Carburetor - slow run

 

In order for the carburetor to get a smooth, even and consistent tick-over, frequent adjustment will be the slow run. It should be made when the engine is at its normal working temperature and when the rest of the machine is in good condition.

1. 1.       Make sure that the throttle cable adjuster has enough slack before starting and running the engine.

1. 2.       Usually, the carburetor has two adjusting screw; the throttle stop and the pilot adjusting screw.

1. 3.       Turn the pilot screw clockwise until it meets light resistance and then turn it counterclockwise one and a half to two turns.

1. 4.       If the motor is running fast, turn the throttle stop until it runs as slow as possible without faltering.

1. 5.       Turn the pilot screw to speed up the engine then bring the speed back down with the throttle stop.

1. 6.       Repeat until the tick-over is right. Adjust the throttle cable to the right slack.
