I've run a mixture of Av gas and 91 0ctane in my 482 bb for some time. Never had a problem, untill. Recently I put 10 gallons of av gas with only about two gallons of 91 octane. Car began running really bad like it was flooding. Problem. Av gas is designed to be run at altitude, thus it has a higher density. If you dont adjust the floats running a high percentage of
av gas, you will have this problem. Once it got mixed with 91 again the car ran perfect.
