Also, on the ignition system, be sure it has the correct coil and/or resistor.
Coils are a common source of confusion.
The coil could be designed to work with a resistor, or it could be the type that doesn't need a resistor.
The only true way to know is the check the resistance across the + and - terminals.
With the coil out of circuit, check the resistance with an ohm meter. Set the meter on a low ohms setting, either 20 or 200 ohms,depending on the meter.
If the coil reads around 1.5 ohms, it needs a 1.5 ohm resistor in series with the wire from the ignition. The end result, 1.5 + 1.5 = 3
If the coil reads around 3 ohms, it will not need a resistor.
Any wrong combination will either result in a weak spark, or a coil that overheats and over amps the spark circuitry, be it points or electronic.
If you do go to buy a new coil, take your ohm meter and check it before you buy. They are often reboxed or incorrectly listed.

Today's Featured Article - Grain Threshing in the Early 40's - by Pat Browning. The setting is rural Wisconsin, halfway between East Troy and Elkhorn, on Hodunk Road, our nation was at war, and I was 6, 7 and 8 years old. George was our "threshing neighbor." He was the one with the threshing machine, a JI Case on steel wheels, and he pulled it to our farm with a JI Case standard tractor also on steel. In those days, steel wheeled implements were common. The roads were general gravel, so the lugs cutting into them wasn't a problem. George would set up the thresher, s
