New parts are in, same problems... I drove around town trying to get a timing light and nobody had one. I decided to advance the timing a few degree's and the truck runs way better, The backfiring out of the carb has stopped. Now it just has a dead cylinder, I think its plug wires.

I got the cheap set from autozone and for some reason they fit horribly, the number 8 plug should be the shortest and the one they gave me was so damn short it rides against the manifold shroud. I got a wire holder for my new plugs but it was missing pieces and i couldn't use it. Im going to try a plug wire set from orileys in the morning and see if it cures my dead cylinder.
