Any thoughts on why ? I started it up drove out of the fence left it run while I closed the gate then it sputtered a few times , I checked the fuel 1/2 tank made sure the shut off was open then it died ???? I checked the plug for fowling cleaned it up with a wire brush and tried it again thats when I found no spark.. I swaped out the coil from my other play toy and it fired right up :wallbanging:

They go bad over time. All the vibrations and the heat. Do you know if it was replaced recently or could it have been on there for years?

Coils have a habit of failing at the most inconvenient times. Just a trait of theirs. No warning at times, when it does give warning, it usually is very hot to the touch.

I am new to working on older engines with coils. It seems like the coils we are getting for GT's today are not that reliable. Being a high voltage device there are certainly challenges to manufacturing them, but it seems like they are the number one ignition trouble spot. Compared to modern automotive ignitions it seems like there is a QC problem with the coils. I guess you always need to have a spare in stock.

The Bosch blue coils are known to work really well on the single cylinders also.

The coil I put on my Bush Hog T-63 is shorted too. I put this used one on it, as the magneto was crapped out. I mowed the yard with it & coil did fine, never got hot at all. Tried to fire it up today & no sparky, plus coil gets hot as a frying pan! It came off a running engine too. They go when they want to I guess.
