Jubilee rebuild

[Jubileejim]

I have a Jubilee ran several years ago but had to leave it for several years. It would not start, then found it had a stuck valve, on number two cylinder. Took the head off cleaned and reseated the valves. Took compression test, but only came up to 30 to 40 lbs per cylinder. I put motor oil in the cylinders, and did the check again they came up to 50 to 60 lbs per cylinder. So now I took the engine out pulled the pistons but three of the four pistons looked to have good rings, number four stayed compressed, I assume from carbon build up. I"m no mechanic, but when I took the head off I had oil on the head gasket where I didn"t think it should have gotten because I did tighten to the torque spec. 70 lbs. Any suggestions or thoughts on this?

Sitting that long is hard on any engine. Oil doesn't work well to unstick things like the rings you found stuck. If you did thing right you probably could have got by with out even pulling the head off. I do lots of engines with the same problem and fill the cylinders with tranny fluid sine it will loosen up a lot of parts. But now that you have it apart you will better off to rebuild the engine and be done with it
