Does anyone make a good coil anymore??
Points? OEM electronic ignition? Aftermarket ignition?
Slant six? 350 Chebby? Kohler 12hp?
Running a ballast resistor?
Mallory Promaster coils work well with points, they were designed when that was all we had.
If you are running a CDI, you need the right coil.
Tell us more about your setup.
