Moron. go ahead and run 20:1 see how long it takes for your motor and carbs to get all gunked up. I run nothing but 40:1 with Klotz tech plate. Personally i think i could get away with a little less oil but im gonna be safe. I can see if your breaking it in and using 24:1 or if your using alky, what is it like 24:1 also?
