Gasoline

Thanks!

What I want to know for sure is if I can I can choose between two different methods to get 3 ohms so that the points will not get damaged.

Alt. 1: skip the ballast resistor and instead buy a coil with an internal resistance of 1.4 instead of 0.7. The effect is the same along with the resistance wire, ie. total of 3 ohms. Also, I know what I get because the ballast resistor increases from 0.7 to 1.5 when it gets hot, which I think could be a problem during extreme summer heat.

Alt. 2: keep the 0.7 ignition coil, ballast resistor and resistance wire that together will result in 3 ohms.
