Engine runs erratic and rockshaft to carb throttle plate vibrate back and fourth. This is worse as speed is increased. If I hold the shaft still with my hand the engine smooths right out. I adjusted the shaft as per paragraph 66 in the service manual but this had no effect. I removed the housing cover and there is a lot of play between the thrust bearing and governor sleeve, flyweights are real loose. Has anybody delt with this situation before? Any help would be greatly appreciated. Thanks
 
Teddy is right. I hae added washers to take out some play. Replace bearing and race if real bad. oldiron29
