I moved the chamber up purposely that is he only way I can see the intake port without moving the chamber up the intake is covered when the piston is at it's lowest position
I know little about these 2 stroke engines. I'm a 4 stroke guy. It looks like your cylinder in not seating down into the crankcase, but is sticking up way high. the shiny base of the cylinder is machined to fit all the way down into the case. take the cylinder off and try to see why it isn't going all the way down. The intake port is not being uncovered fully when the piston is at bottom dead center. Good luck.
