Ok. But since I'm a newbie.......how do I find out if the exhaust valve is open? That would when the piston is at the bottom of the stoke? The exhaust valve would then be fully open? What I was trying to do was bring it to TDC and either suck it out (doesn't seem to be working) or loosen it up with air from the compressor. I can't see it thru the spark plug opening either way. Going back to tackle this again for a while. Thanks for your input, I'll give that a try.
