The piston draws fuel into the crank case through the crank during its upstroke. As the piston moves downward the fuel in the crank case compresses, once the piston hits bottom dead center it passes some ports on the sleeve. These ports inject the compressed fuel into the cylinder. The piston them moves up and the cycle repeats.

Technically, a glow powered two stroke is rotary valved, because of the intake tube that runs through the crank, which has an opening that allows fuel/air into the crank case once per complete rotation.
