If gague is working compression WAY low should be 150-175 I'm surprised it runs. Have you checked for timing stretch ie. Wear and lots of play?

Don't think gauge is accurate but they were all even. Starts and idles to good no miss at idle

I think I am having the same problem. If you press the trhottle does it die?

Does it free rev and the transmission does not want to shift? Almost like you have no 3rd gear or does it go when you stomp on the gas but still runs like crap?

That's what I am dealing with now

Try the rotor (the thing that spins) with the distributor That's what was wrong with mine. Runs smooth as day now.
