    So I was riding and my engine cut off when I engaged my clutch and came to a stop. I tried to start it but after the sound of,the combustion, nothing happened. Do I need a new spark? Its,pretty old.

    spark plugs fail, but not too often - never hurts to buy one even if just for a spare

    look thru the "no spark" troubleshooting steps

    If it's one of the two-strokes, I keep hearing how the kill switches can be a pain also. I replaced mine with a toggle switch from Radio Shack right from the beginning so I've never had to deal with it, but I've heard other people having trouble with the cheap ones shorting out or failing to work at all.
    Have you pulled the plug and, with the cable on it, held it to the head to check for spark? If not, the plug and the kill switch are some of the cheapest fixes you can do.

    I use my choke to kill the engine. I accidently broke a wire from the kill switch so only the black wire remains in tact. I put the spark plug to my engine and pushed and saw no spark for the plug. So I assume that's the problem unless this is not what you are asking me.

    It could also be that the magneto is bad. Was it by any chance raining or wet when the engine died? If even a small amount of water gets in the magneto housing it can ruin them.

    I have an oil leak problem from my exhaust gasket being bad until my new ones come in mail today. Oil may have gotten into it which god I hope isn't the case, I should have bought a spare box.
