What I have found is that sucking or blowing in the governor tube will raise or lower the revs, the throttle control does nothing, so this to me indicates the problem is inside the crankcase, does anybody know what controls this inside the case? The one Bumps is working on, he has the hose coming up to the fan on top of the motor. He is working with, I think a full crank motor he has adapted to use an LM carb. I'm working on a number of Powertorque motors
