[Fot] Ignition coil for 6 cylinder with points (racing)

[Bill Tobin]

Jason, sounds like you have too much current going through the points. 
Maybe try an external ballast resistor. (Ask me how I learned this!).

Why not go Pertronix or other pointless distributors? KISS. But always 
carry a spare!

Cheers, Bill
