Thanks for the replys guys. Well I did a compression check on the engine, and my worst fears are realized. #3 cylinder has no compression. It is not just down on compression, but actually has none. Won't even move the gauge a little bit. The other 3 cylinders range from 170 to 180#. Looks like the engine is coming out and the head removed to see what is going on. If this thing wasn't so nice otherwise, I wouldn't bother, but I can't just knock it in the head. It deserves to be fixed.
