Look for a wiring diaghram for your motor, or something close in year on the maxrules web site. The usual spark killer is to ground the black/yellow wire at the ign key.

Like Chris said....black wire with yellow stripe at the switch box on side of engine. Disconnect that and touch it to metal on motor while running and it should stall. If it doesn't, the box is bad. If it does, ground it at switch to see if you have wiring problem or faulty switch.
