These carbs had a lot of vacuum leaks and fixes for them. Chrysler came up with a brace that fit accross the top to try to squeeze the top down more. You probably need a rebuild now though due to the alcolhol that is intodays fuels. The alcolhol effects the accelerator pump as well as power valve in the carb. Te newer parts are effected by the alcolhol.
