I’ll check again but the way I did it when the intake was going down and starting to head back up I stopped at the T and the three holes were lined up as well. I’ll check with a straw as well. I added the oil in the plug hole and still no compression. Piston is going up and down. Do I need to put the valve cover back on to check the compression? Didn’t think it would matter. It’s nuts that it has zero compression..... what the hell would cause that by adjusting the valves. Ran decent but hard start and didn’t idle good. I put air into the plug hole and it seems like it’s holding since I have to push hard on the nozzle to keep it in the plug hole.
