Backfire
My truck backfires bad, so I adjusted the timing, and made it worse. is the timing the only thing that causes backfiring. Its pretty bad, shot about a three foot flame out of the carb, so I gave up for the day. I will get the damn running good, eventually.

Backfire
A backfire through the carb can only be timing, yes. if it were backfiring in the exhaust, it would be a fuel problem. does it run rough and then die or will it just not fire up at all now? the only two things i can think for you to do is...1) check all the plug wires to make sure they are in the right order. 2) find TDC by pulling the #1 spark plug and feeling for the air rush on the compression stroke, then watch the timing mark and line it up right on 0....now set the distributor so that the rotor is right underneath the #1 contact on the cap and after it starts, (hopefully) adjust the timing more from there. if you do this and know for sure that the timing is set right, then you can start to worry about malfunctioning parts. i once had a distributor that was bad and had the exact same problem.

Backfire
All the internal parts of the distributor are new as well as the cap. It did used to backfire out of the exhaust, but since it started going through the carb, I haven't checked. How do I fix exhaust backfire.
