I am looking for help on the ignition system for a Tecumseh hh100 engine that is in my Custom 10 XL. This is giving me real fits because I drove the tractor inside the garage, it sat for maybe 2 months, now I can not get it started. The first thing I discovered is the engine in it is not the original, however the shroud over the flywheel is original. The shroud says it is electronic ignition, but the engine has a coil and condenser under the shroud and a set of points on the other side of the engine. I think the problem is in the coil, but I do not know how many Ohms it should read. When I first started checking it out, I read less than one Ohm at the input and infinity at the plug wire. Then the plug wire actually came out. This is an encapsulated coil, and when I looked into the hole where the wire came out of, I saw like a tack point in there. I then measured the coil into that point and it reads about 8.8 k Ohms, so I checked the plug wire for continuity and it read OK, I mixed up some epoxy, being careful that I did not get any on the point in the hole, I put the plug wire back in and left it sit for 24 hrs. I then rechecked it, reading from ground to inside the plug cap and it again read 8.8 k Ohms. I thought I had it solved, reassembled everything and tried it, however it did not start. I then put an inline spark tester light before the plug and it was very dim. I took out the plug and grounded it with a large wire jumper and tried cranking it, on the first revolution of the flywheel, there was one nice spark at the plug gap, then nothing. My main job is industrial electronics, so I got my capacitance tester and checked the condenser (capacitor) and it measured .25 micro Farads, not knowing what it should be, I took another .25uF capacitor and tried again, with the same results, first revolution, one good spark, then nothing. I then tried going up to a .47uF capacitor with the same results again, one nice spark then nothing. Here is where my biggest problem is, I wanted to buy another coil to try it, but I can not find one anywhere. I tried the internet, all the local mower shops within a hour, from where I live, nobody has one. If anyone could direct me in the right direction, it would be most appreciated. I live about 50 miles North West of Philadelphia, PA.
