HELP! I have a 1985 22r. I was driving down the trail, and all of a sudden lost all power, the truck completely shut down. I put it on the flatbed and took it home. I looked at the distributor and the rotor was destroyed and parts were melted to the cap! I've never seen this before. I cleaned everything out, replaced the pick/up coil/magnet, set the air gap at .3, replaced the rotor and cap, put all new wires and plugs in it, and attempted to start it up. It wouldn't start. I wasn't getting spark. So I checked my coil, and it tested out of spec, so I replaced it. Still nothing. So I bought a used ignitor, and it fired up, but it ran like crap and wouldn't idle unless I kept it floored. I figured the timing was off, which is strange because it ran perfect before all this happened. The only way I could get it to idle was to advance the timing about 15 degrees. (timing mark on harmonic balancer was 15 degrees to the right of the 0 mark). I thought, maybe I skipped a tooth on the timing chain. So I pulled the valve cover, and aligned everything to TDC. To do this, I rotated the motor so the bottom was lined up at 0 (12 o'clock), and the cam dowel was at 12 o'clock with the dimple sitting about 11:45. The rotor lined right up with the #1, and I pulled the #1 plug just to be sure the piston was at TDC. Everything looks to be aligned, which leads me to think my chain is fine. Also, the guides look good when I look down from the top, and I've never heard any slapping from the chain, so I don't think the timing chain jumped a tooth. next step was I bought a rebuilt distributor from NAPA. I put it in, and nothing.. no spark or anything. So, I pulled it out, and put the old one back in. I got spark, but it again ran like crap... so the new distributor was crap. I pulled the pickup coil and magnet out of the old distributor (because it was new), and replaced it in the new (rebuilt NAPA) distributor. it started and I got spark, but it still ran like crap. Same as the old distributor. It idles fine, but only when I have it 15 degrees advanced, and if I try to drive it, it backfires through the carb and tries to die whenever I push on the gas. I had to engage the crawl box and put it in low 4 (two cases), just to get it off the trailer and into the garage on a flat driveway... I also tried moving the distributor up and down a gear notch to see if it changed anything, one way it idled much higher, but timing was way off, and the other way it wouldn't even start.
I'm at a complete loss... Any suggestions?
Thanks...
