Have your switch cut off the main relay which will kill the spark. Make sure the car is out of gear to keep the engine from spinning any more than it's own momentum causes.

WARNING:
Remember that your carb will still be providing fuel to the engine even though no spark will be present to detonate it. This will push a small amount of unburned fuel into the exhaust system. Restarting the engine may cause a small backfire. The more the engine spins after the spark is cut, the larger the backfire.
