Throttle coke

Tightening the clutch will not reduce the idle speed. In this case, first check whether the idle speed is too high. When the car is hot, the idle speed should be 1500 rpm. In addition, check whether the throttle pipe and throttle handle are stuck, and whether the throttle of carburetor is stuck (this is easy to happen if the gasoline is not used well). Check whether the carburetor mixing ratio is improper, whether the valve clearance is normal, and whether there is slight air leakage in the intake pipe and valve, which will also cause no load (this will happen if the gasoline is not used well).
