Ok, so I cleaned the piston top real good and used a new gasket. As far as the combustion chambers, they all looked clean and smooth so I didn't do anything to them. I did remove all the spark plugs but didn't squirt oil in them or have it rotated perpendicular. I can try that this afternoon. So as far as adjusting tge valves goes, I messed with them, lol. So I watched several videos, none of them made it as simple as tighten to 20 ft pounds. Some said tighten until there is drag on the rod then go one flat. Saw another guy tighten until he couldn't turn the rod and the he would go a fullv3/4 turn on the jam nut. Spin the balancer 99 degrees and repeat until he couldn't spin them at all while tet another individual tightened them where none if the rods would spin then backed it off till they did. So I ended up somewhere in the middle. I tightened them till there was drag spinning them and then added a flat. Looks like I'll do some adjusting and retesting later today. Thanks for the knowledge
