I figured this out a long time ago and just used it again today. Every once and awhile, the battery goes dead on my RK-21 so I have to pull start it. HINT ! Remove the kill wire from the oil pressure switch under the engine. You'll never get it to fire up with the recoil start becasue you can't spin it fast and long enough by pulling to build up the oil pressure to open the switch and allow the plugs to fire. Once engine is running, reconnect wire to be safe.
