Old, apologize, wrote my posting as I was headed out the door. Converted my 300 to 12v a few years back. I have no ballast resistor, just a 12v coil. I am suspecting the coil (HV side) may be faulty cause when I try to start in the am it will run very briefly then shut down just like the ignition was turned off. Ran all the checks, 12v on the coil, points, condenser, rotor and cap all new, switch and wiring good. I do have spark from the secondary to iron, but it is kinda yellow/orange and battery full charge. Ohm meter says primary windings look ok. Late last night I could not see fire at number four plug when removed and grounded. When the rain passes I will check the plug wires and with the spark tool see what it looks like at the coil and end plug wires. Thanks for the info on 12v coils, did not know there was different types of wire that present resistance.

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
