I'll probably buy one of those units that fits under the distributor cap. I had some electrical schematics to use the points, but run the wire from the coil through a MosFET to do the switching. The spark of any coil will greatly be increased if the points are not used to make and break the primary circuit on a coil. The points will only be used to signal the MosFET to do the switching. If done this way, a home solid state ignition can be made for less than $15 in parts. With principle of inductance as in a coil, the faster the current is shut off, the greater the intensity of spark. When mechanical points are used the arcing begins before totally opened, and the "shut off" is not as sharp. That's why you can only gap the plugs at .025" with points. When solid state switching is employed, the gap can be geatly increased to .040" and upwards to .060". Using a solid state off of an auto I think is too bulky and awkward. I think I would only consider using an HEI off of a GM product if I would ever try it. The other manufacturers used auxilliary boxes. For my John Deere 3 cylinder, I would have to one off of a 6 cylinder. I would probably take the whole 6 cyl distributor and make it fit onto the cam gear and engine block of the John Deere. Just use every other spark plug wire location and remove every other pickup projection on the shaft. Ken McWilliams

Talk of the Town: How to Remove a Broken Bolt - by Staff. Another neat discussion from the Tractor Talk Discussion Forum. The discussion started out with the following post: "I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
