Problems with my Slant 6

Apparently I was way off in what was wrong. I have my car out at my parents place, and my dad thought the timing chain skipped. Well, what actually was going on was way too much fuel was going into the cylinders and making some pretty sweet banging noises. Little tuning of the carb seemed to fix everything. Apparently my reverse just disapeared on me though. Yeesh, time to take the tranny apart.
