no spark kohler twin

Recommended Posts

Just bought this tractor (Deutz-Allis 917 H) with mower, tiller and blade 3 weeks ago. The Kohler twin 17 (KT17 series II) ran nice and smooth for a couple short test drives after I brought it home. A few days ago, I tried to start it, it died after a few seconds, then wouldn't start. No scary sounds or anything, just stalled. I figured I had flooded it so I let it sit. Anyway, no spark still. Have put a new capacitor on and checked all connections. Guy who sold the tractor to me said he had replaced the circuit breaker before I bought it. I Can smell fuel when I crank and I can heat up the coil if I leave the key in the run position, so I know I'm getting fuel and I think my ignition wants to work. Here's the scary part. I took the cap off the points and when I crank the engine, I don't see anything happening there as far as pushing the points open. Should I be able to see this process, or is it too subtle for my "bent over sideways in my dim barn" observation? Also, as I pulled the points (replacing the worn out gasket underneath,)the plunger that (I would assume) pushes up on the point armature wanted to come right out (I didn't let it). Is it supposed to be like that? Or am I knee-deep in doo-doo? Thanks. Tom in Ohio

If the coil heats up but you don't see spark at the points, check the point gap and clean the contacts with sandpaper. If still no spart, look for a shorted wire between the points and coil. Condenser could have shorted internally. Coil has to be grounded to heat up. Points supply the ground, or condenser has shorted out, or wire shorted.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
