gmc, You might try loosening the 2 screws where the throttle shaft tube connects to
the carb and remove the 2 flange screws on the vertical housing. Slide the flanges
away from the housing and tighten the screws at the carb. The tube should not be
tight against the opening in the housing. If there is a problem , you'll need to
clearance the hole so there is no binding. Do you have an aftermarket manifold? Have
you replaced your horizontal throttle shaft? Just a couple things that may contribute
to the problem. Bob
