My 1990 Indy is spitting fuel into the air box and starting the air box on fire. I had this problem last year after it was running great, this year I cleaned the carbs and changed the spark plugs and got 40 miles out of it before it started spitting fuel into the air box again. It is only spitting fuel out of the left cylinder, I tried switching the carbs around but it is the same cylinder every time. Any ideas??
