backfire and bb's on tin roof
are these signs of detonation? i hear the backfire mostly when cold and under hard acceleration. the bb's is under light load in lower rpm's i can hear it pretty good. i have used both super and regular gas with same results. any ideas how to fix or if running bad?
thanks, jim
