True, tdc will tell me if timing, I'll hit that up with the others. I do agree on the balancing too. When I engage the clutch, there is a jarring shake, then it smooths out till about 1900, then it has this high vibration, doesn't shake the jeep like the start off, but just vibrates to the point of concern. I can drive him, I just shift real low. If I am in n, and I give it gas, it vibrates and holds true not wanting to go above 2000. Did this clarify? I am just torn, doing a poopie load of troubleshooting to find the problem and make the ill motor better or just get a reman, replace the clutch, flywheel and mounts?
Personally I think your jumping around looking at stuff that may not matter at all. Your engine is not running that well but it does run. Large vibration concerns
as you have stated are normally external from the motor unless you have a broken rod or crank. Yes timing could be an issue and No question it is hard for anyone to diagnose this over the computer but if it was me I would have already had it up on TDC and either pulled the pan off or I would be looking in that clutch can for answers.
