Once the throttle shaft has been seated, Jim twists in the throttle blade screws. It would seem that Loctite would be a logical solution to keeping these screws in, but this chemical can migrate to the bushings, causing the shaft to bind. Instead, Taylor peens the throttle blade screws to prevent them from working out and falling into the motor. He accomplishes this task without bending the delicate throttle shaft by mounting a homemade screwdriver head into the vise, setting the throttle flange on top of it so the blade is in the screw slot, and tapping with a small hammer. This method prevents pressure from being exerted on the shaft.
