loquin Thank You for this. I was a bit worried too but then I also noticed the cdi and coil is the same unit. Nevertheless I still use the choke to shut her down. It's cooler that way. To the average person staring at me it makes me look like I know stuff and that makes me fly.This shouldn't be a probem, fetor. IF the coil were some sort of secondary coil, where shorting it wouldn't kill the engine, then it WOULD be a problem. The amount of current would cause the coil to eventually heat up & fry.
However, when you short out the coil, the motor stops spinning in a few seconds. There isn't enough time (or current) to cause the whole coil to heat up enough to cause any damage. If 3 watts is the upper limit before the engine is affected, 6 watts should be enough to kill the engine. So, we'll assume 10 watts. Take a look at a 10 watt florescent bulb - place you hand around the bulb and base, and turn it on. How long before your hand gets warm? A minute? 5 minutes? The amount of mass to heat up is about the same as a coil of wire. Plus, the coil of wire is wrapped around a lump of laminated steel. There's a LOT of mass there, and not much power to heat it up...
