Can you rotate the engine? A stuck valve will often stop the engine from rotating, either because a piston hits the valve, or the cam lobe is prevented from turning.

If the engine is rotating normally, try squirting a tablespoon or so of oil into the two cylinders without compression and see if that makes any difference at all.

Make sure the throttle is wide open or you will get a false reading. Which 2 ??? After 3 years could be rats, dirt dobbers or something else in exhaust. Be sure to check breather before it sucks junk into carb.
