You will stir up a hornet's nest here with your question. I have changed 2 tractors from 6 to 12 volt- grnd with an alternator. Both tractors also have EI. My 430 JD never cranked very fast on 6 volt. I had a generator go bad on my MT so swaped the generator from 430 to it. I think I got an alternator from a wrecking yard, but even new they are cheap. It starts really great now. I do use lights and much easier to find 12 volt lights than 6 volt, and the alternator keeps the battery up even with several lights. My other conversion was an SMTA. I had experience with Farmall Ms before that generally cranked really slow so converted it. With it I used a resister ahead of the coil until I converted to EI then went with coil Pertronix suggested. The 430 had a fairly new coil with internal resister so used it that way when converting to EI. Make sure you get the right unit for you voltage and ground on the EI as they don't like to be fed the wrong voltage or polarity. My guages worked ok as they weremanual, just put 12 volt bulbs behind them. If you have a fuel guage that may be different. There are several good wiring diagrams in archives her, I used the one by Bob M. Generally not to hard to figure out alternator mount, on the SMTA I just turned the stock one upside down.

I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
