Thermoquad Problem
Mike, what are the numbers on the carb. You'll find them on the drivers side carb pad, the vertical surface.
Secondly, is this a reto or a (Minus the intake) job or a HP build?
IMO, I'd return the carb and go here for your T-Q needs.;

and tell'em we here @ FABO sent ya.
This fella is very very good with the T-Q carbs and can ethier rebuild what you have and retune it per your build, sell you a proper one for the task at hand.
