Re: Can a 2-stoke engine still run when bike is stopped?
Pulling in the clutch DISENGAGES the engine from the drive chain allowing you to freewheel the bike. It also allows you to get up to speed before popping the clutch to start the engine as opposed to trying to cycle against compression of the engine at a dead stop. When you stop the bicycle you should be pulling in the clutch at the same time as the brakes.
The idle adjustment is a screw on the side of the carburetor.
