Being a 2 cycle, probably turbo and blown intake system. it is possible to get a runaway engine. It happens if there is an introduction of oil (fuel, crankcase etc) into the air intake. Any oil will become fuel and since the air intake is always wide open if there is enough of a oil leak it will keep the engine running. There is a drive link for the blower which is designed to fail before engine damage occurs. If there is a kill switch on the dash, it will be a damper that blocks air from getting into the engine, thus shutting it off. It sounds
worse than it is, just be aware of the intake air blockage method.
