Put on an electric fuel pump and shut it off and let the carbs run dry before turning off the ignition so when you restart it the bowls will have nice cool fuel in them
Or put a regulator on a return after the carb. This stops the flooding issue caused by vapors holding the fneedle and seat open. Most all cars with out a return system will do this. It is common with ethanol. Methanol is even worse . Fuel injection is the way to go I am switching my duster to port injection when boosted. Steve
