hi guys, ive got a '92 model YJ that i plan to rebuild but i have no idea where to start. a little back ground on the vehicle, ive had it for almost 4 years and at first it ran like a charm (has small block 350), but after the 1st tune up its not been the same...it backfires thru the carb, has gone thru 2 starters and 2 batteries, it will run but has to be jump started it has trouble cranking if you just turn the switch (this is even a problem with new starter and battery). it really is a pretty bad ass mud rig, along with the small block 350 its got 4" suspension lift and 3" body sitting on 35's. i really want to get it back on the road but i have no clue where to start. any of you guys have any pointers? thanks in advance.
