Hiya ric,
The problem here, of course, is that your carburetor/intake manifold set-up was never designed to run with an alternator. I'm guessing that you need to clearance the accelerator pump arm. Correct? I'm also guessing that you are running a 30PICT2 or a 30PICT1. I have heard of folks getting the clearance they need by grinding away a small part (the contact point between the carb and the alternator) of the alternator body, but without specifics I really can't tell if that would work in your case.
