Hi, I have been having some minor problems with my carb on a retrofitted '83. It is the factory Carter BBD, 8381S, 2bbl. I rebuilt it about 5 years ago. Now I'm starting to get a lot of stumbling on acceleration, especially when cold. Not too bad when warmed up. I tried Dick Benjamin's trick of slowly moving a piece of cardboard over the intake and lo and behold when the carb was about 7/8ths blocked off, the rpms increased about 50 and the idle smoothed out. I have checked all the rubber hoses (I think) and they seem to be fine. Any ideas where else the leak could be? I was thinking of re-tightening all the carb screws and mounting bolts.
