So i had to pull the head on my 92 22re Truck and I'm just about finished except i cant seem to get the timing right. I don't know to much about timing except that you start at TDC and line up distributer cap at the #1 sparkplug. after that I'm pretty much stumped. So far the best i have got was it started up but wouldn't rev past 1k. since then i have messed with it a bit and now all it does is backfire. any words of advice?
