So I have just tested for leaks by using a tuba attached to the intake and putting the piston at top dead center and there are none. I am also very confident that the head and base gasket are not leaking. Nothing seems to be wrong! I am absolutely stuck. The one last thing I will try is sealing up the top port and try to start it because maybe I ported it wrong? Even though it ran perfectly after I ported it and only went down the shitter after like 30 more miles. So for today I’m done and i might just have to bite the bullet and get a new cylinder because as far as I know that’s what’s wrong. Here’s a photo of the cylinder if that helps.
