I pretty much agree with JimN. A few comments however based on my experiences:
1 – If you open the plug gap make sure the plug wires, distributor cap and rotor are all in excellent (eg. “new”) condition and are scrupulously clean. Otherwise moisture, dust, etc. may cause arcing somewhere you don’t want and you'll get misfiring. (Keep in mind the stock cap, wires, etc are designed for only 15,000 – 20,000 volts max.)
2 – Don’t expect any noticable power improvement from the flamethrower coil. You MIGHT see a % or two on a dyno. But you’ll never feel it in use.
3 - At the RPMs and compression that your modified H engine will see, the stock 6 volt ignition system - IN GOOD SHAPE AND PROPERLY MAINTAINED - will be entirely adequate.
4 - The real advantage of electronic ignition is it is essentially maintenance-free. You'll no longer have to deal with weak spark, timing drift, etc. caused by point and rubbing block wear.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
