how do I set the timing (won't start)
I've been told that the timing is off . We changed head and apparently the exhaust is opening just a little to soon and its backfiring. I get a small puff of smoke out of the air intake. Dose this mean that I could be off one or more gears on the cam. If so what is the correct steps to allen and time it. 1998 Chev tracker 1.6 16 valve motor with internal coil in distributor if that matters
