8n carb/gov speed

Take the link loose from the throttle lever to the governor and then see if it will let the engine idle right or lower. If so look at the linkage at the bottom of the throttle rod where the link from the governor connects and make sure that the clamp bolt is tight and in the right position. There is a flat on the rod coming down that is supposed to hold the throttle lever at the bottom in place but if the clamp is loose or of the lever itself is bent which is possible you may not be able to bring it back to idle.

Also carefully inspect the carburetor throttle shaft where it enters the carburetor. The little lever with the ball on it is bradded onto the throttle shaft and this connection sometimes loosens and allows the lever to move but the throttle shaft itself to move less than it is supposed to. Sometimes you can remove the carburetor and peen the end of the shaft back enough to tighten the connection and sometimes it is necessary to braze or silver solder the connection back so it is firmly attached to the throttle shaft.
