Tell me whats wrong please...
Hello all. This is my first post. Here's my question. I have an 83 bronco with a 351w in it. I bought it at a pawn shop for $1200.00 and had some front end work done on it. At the time I bought it it ran (if you want to call it that) but back fired ALOT. It has alot of mallory items from the distributor to coil to ignition. I put a new dist cap, rotor button, plugs and plug wires and it calmed down a bit of the backfiring but after only 35 miles of driving it started again. I pulled the plugs and after only 35 miles they are covered in black soot. So I figured the carb ajustment was off
(Its a Holley) and drained the oil (stunk of gas) and filter and put in new plugs. Ajusted the carb until the backfiring stopped and it runs better but after only 20 miles the plugs are covered in black soot again and it just doesnt run well. Does this sound like the carb is shot? Any help is greatly appreciated.

I've never seen a pawn shop sell trucks, but thats cool. Not a bad price though.
I would say the rings are shot, that would explain the black soot and gas in the oil. That would call for an engine overhaul. Also the back fire would be the distributor way advanced, or retarded. And the carb could probly use a rebuild. You got yourself a real fixer upper.
Sounds like fun to me. 
Good luck bro.
