The truck has a 370 in it, new carb. It runs out pretty good it just has some backfiring in the intake and occasionally a big backfire from the exhaust. I'm trying to check the timing but I don't have the specs. Should it be timed at 10 degrees? Also, what is the air/fuel mixture or a good starting point? Both are at 1 1/2 turns out right now, should it be less?
have the same problem?
