i just swapped out my ls for a b20 and i have had a no start for the past three days... i have readjusted cam(valve) timing about 4 1/2 times and it was dead on 3 times and still had a back fire out of intake(fireballs) and exhaust (Pop) hrrmmm... i am quite frustrated, i have a good strong spark from my old Ls dizzy, getting air in through my open 58mm throttle body, and the fuel is causing all sorts of bangs pops and what not sooo it just is not timed correctly somehow. i still think somehow the dizzy is to blame whether it b not timed right or maybe just off a little, but it still should run even with whacky *** ignition timing, o well if anyone could give me a hand id appreciate it
