Ok , did a compression test today with a proper tester.ALl are within specs although 5 and 6 are just a hair lower than the others.Its still starting and running like a top.Haven't had a chance to take it for a spin yet to see if its still got no power.I also fixed my electric fan while I was out there.It wasn't turning on due to a bad fusible link.It turns on now , so thats a good thing.I have no idea how to tell if a lifter or something is sticking , or even a valve.2 of the plugs did have a little black on them , the others didn't , so I take it to mean that 2 cylinders are burning a little rich?
