put the electronic ignition on my super 55 2+ years ago and she has always fired right up, even when -20 degrees.

last week when plowing snow, she started losing power, especially going uphill, and backfiring handsomely. I also noticed sparks arcing out of distributor cap. muffler and exhaust manifold glowing red (magma) color.

i changed plugs, new plug wires, ect and she still fires right up and idles beautifully (great oil pressure too.)

this morning, after about 15 minutes of plowing she started the hiccuping uphill and quit. Got her to fire a few more times but a very, very rough idle and will not come up to speed. she coughs and sputters and quits.

does this sound like a coil that is going bad? tractor always fires right up. then when getting up to temp and working i lose power, she backfires and tries to quit. if i hold the clutch in she sometimes comes back.

any help appreciated.

Check your filters, and carb jets for plugging. If nothing, readjust your carb to factory specs. A lean mixture will backfire handsomely. Check your plug wires for high resistance. Mine started running rough and backfiring when one of the wires corroded.

If you had sparks arcing out of the distributor cap, it dos not seem like a bad coil. More like moisture in the dist. cap!
Have you checked for tracking inside the cap or for cracks in the cap? Spark may be tracking across to another plug and causing backfiring.
Could also be condensation on the fuel side causing problems? A very hot exhaust could indicate retarded timing, burning fuel in the exhaust manifold or too lean a mixture.
Have you got the correct type of plug lead for your electronic system? The electronic systems can easily destroy some of the carbon fibre plug leads due to the extra spark enegy.
Check to see how long a spark you can draw from the coil when the trouble arises. A good long blue spark would indicate the problem is elsewhere, a weak yellow spark would indicate an ignition fault.
Ketteringham system ignitions are so simple and easy to fault-find, electronic modules may be a whole different ball game.
Hope this helps you to sort where the problem is. Get back to us if you cannot sort it, and get back to us if you find the fault - that way everyone learns from your problem.
Regards, RAB
