RE: general timing question By Gerry Proctor - 10/16/2003 8:08:24 AM; IP 207.133.188.254 Ten degrees BTDC is more advance than six degrees BTDC so you have that part right. As to the popping... Where is it popping? Out of the intake or exhaust? And is it a stucatto of pops (a lot of rapid closely-spaced pops) or is it just a backfire pop that occurs once or twice on throttle application? If it's out of the intake it could be that your lifters are pumping up due to having too much lash or you have a lean backfire. If it's out of the exhaust, it could be that your timing is too far advanced (you can't put too much faith in the ignition timing mark on the damper since these commonly slip with age). None the less, solving your popping issue should be relatively easy. You can retard the timing some to see if that helps and if it doesn't, you can relax the lash on the rockers to see if that helps. If it's a lean backfire, you'll have to investigate the carburetor for pump shot or investigate a vacuum leak.

This thread, so far...
