Hello; first of all, thanks for your help with this engine. Yes it still has that tight spot at TDC. Whenever it stops, it seems to stop at TDC and it's hard to turn the prop either direction. Also the needle valve was loose, but because of the way the engine is mounted, we couldn't get at the screws to tighten them up. We tried to tighten the head screws, but it didn't stop the oil from the head.
