Hello. Here is what happened.I got this jeep 4 weeks ago. My mistake.I drove it home on the highway for about 150 miles. Went out the next day to take a ride. Went about 15 miles and at about 40mph it totally locked up the drive train. Got it home and found the t150 seizqd up. Replaced tran, with same. Jeep only has 66000 original miles, didnt want to take away from originality. Then jeep would start. Did some tests and replaced cap, rotor, distributor, module, solinoid, cables, rebuilt carb, etc.I wanted to start fresh. Did further testing and found excessive timing chain wear. When trying to time jeep the timing mark on the damper was 1 1/2 to 2 inches below pointer on timing case. Replaced timing chain, did the install test and had 22 pins between mark on cam and crank gear. Reinstalled distributor and stared, but the timing mark is still in the same pcsition with light.I thought maybe the damper spun, but with piston on tdc the timing pointer is ot tdc. It would run but not smooth, it idles okay at points, but when reved up, it will pop through exhaust and sometimes the card. The compression all all cylindrers is 139 to144. Then I tested power from ignition switch to through the complete starting and ignition system. Found power in all, even - side coil blinks when tuning over. Tells me distributor trigger wheel is working through pick up. Now when reassembled it has no spark.I need to fix at least two things here, intermediate spark plug firing, and timing issue.I am a disabled, but have been a certified mechanic for 25 years, just dont do this everyday anymore. I have forgot more than I remember. So I thank you in advance for any help you can provide. Sorry for length of question. Jim
