Depends on the engines ignition system. If its electronic (no points) there is a hookup on the coil when you use a wire to hook this tab to ground (engine block or cart frame) the engine kills itself. I cant remebwer how points are setup ATM but im pretty sure you gotta pull the flywheel if one isnt already hooked up (wire coming out of the engine).

No, that would put 20,000+ volts through wiring rated for less than 6, BAD idea. Not to mention most switches have a gap in em small enough for a mag to jump. You have to ground it on the low voltage side.

Yes I have learned the hard way in my dragster. It wasnt exacly from the spark plug tip. My coil has a low and a high voltage kill switch. The low voltage wire can be used with a normal switch. However the rules state that we must have a electrical switch AND a mechanical electrical. So I had over 40 thousand vots going through a normall switch in my cockpit. As soon as my dad started me up and I gave it the gas The throttle wouldnt even work. It was just dead. And you get the biggest shock of your life shutting off the car.

Mech kill: reach back and pull the plug wire off.

haha not good though if you dont have a plug boot

Good point, my flathead has a built in spring loaded arm on the head that touches the bare plug top and kills the motor. Or if you lack that neat feature a "old school" sheet metal strap on the nearest head bolt works.

First you gotta pull the cooling blower shroud/pull start off 9if there isnt a wire sticking out of the motor.
Then you need to ID the ignition system, wires running under flywheel=points, no wires to flywheel=magnetron.
If its a mag there should be a tab for a small blade connector, when this tab is connected to ground the engine ignition is killed.

I like karts
Rotary Power!
screwdriver. touch it to the head and plug top if there's no boot

If i think about it i will get a pic of a electro ignition coil.

Not good enough when your doing 90 MPH and my arms are strapped in. By the time I got my wrist straps off I would be at the end of the track crashed.

Crashing is you foot and brains fault, your better off WITH THE MOTOR RUNNING if you feel in danger of crashing, especially on live axle setups where good throttle/brake pumping timing is everything in sharp turns. Only time this isnt true is if your trans locks up or your throttle comes unhooked and the motor runs away.

How much did the crash set you back? LOL
Gotta be careful man, how did you manage to crash anyway?
the bumper helped and the throttle got stuck because we still havent added the pedals or brakes we were doing it the old fashinoned way by doing it by hand and my brother who was pulling the throtle just it it run away i was inside a very large shop. The key out of the sprocket fell out and it was still going i think it was being held by a set screw
