12a Backfire issue
I did search around to find a answer but got nothing so here it goes, i have a 79 sa22c and its only got 46,xxx miles on it. it ran fine until i tried to experiment with taking off the exhaust and leaving it with just a pre silencer. every time i let off the gas it constantly backfires extremely loud until it reaches idle, i know the loud part is from lack of muffler but it shoots giant blue flames (that's cool and all) but its too much. i can post a vid of it doing it from in the car if needed. Thanks!

Probably running rich due to lack of back pressure. I would say timing isn't an issue if it started after removal of exhaust. I have had two first gens with modified exhausts that ran great but backfired under deceleration, resulting in the infamous 1st gen flames.
