I have noticed several Mc 15 saw motors used for karts. Does these have only 2 exhaust and 2 intake ports drilled? Are the third transfers left blank?

The old Mac 15 was 80cc greatly detuned saw meant for the consumer market ya know not enough power to pull the skin back on a rice puddin' but they did last and there were two ports left closed.
