So i recently got an 88' Ram 50 4x4 (has the 2.6L I4) that sat for at least the past 12 years without running (last registered in 2000). The body is in perfect condition, the engine would only turn over and not even try to start. I've put in a new distributor cap, changed the oil and filter, new fuel filter, put the firing order in correctly (was at 1-2-3-4, now at 1-3-4-2) and pulled the jet valves, as one of them was so covered in carbon build up it wasn't springing back like it should, and put in an eliminator kit. All of this has helped and it starts up and will run, not well though. It has a bit of backfire out of the carburetor, and wont idle at all. It starts hard, shudders a lot, and will only stay running at higher rpm's. This is a pretty broad problem, but I'm fairly stuck on what to try next. Any suggestions?
