If the seal leaks, the crank case doesnt build pressure up like it should and the cyclinder ports wont suck as much as they should. two strokes rely on pressure to run right.

Little RC car motors are notorious for this too, the bearing seals leak a tiny bit or the o ring around the carb leaks and your fucked… it will never get or hold a tune.
