There is alot of info missing. Did you simply swap the carb and fuel? Did you make timing adjustments to compensate for a slower burning fuel? What type of carbs? Jet size? etc? Did you switch to pump gas or race fuel? Alcohol burns cleaner and faster. If the car was set up for Alky it takes more than switching a carb to get the same results.
