I have 1990 rs camaro, 400 small block engine built by someone other than me.
I had my carb replaced with a 600 holly, now all can smell is gas and I cant adjust the carb or even adjust the idle. I see black smoke when start the engine. I believe the engine is bored to 40 over, cam over 500 lift. carb sits on a mid alumnium intake, I know nothing of the heads. Im thinking too much carb for not enough engine, anyone have a solution?
