I converted to a 12 volt battery, points, capacitor, and 12 volt coil. I used the original capacitor that was used with the magneto and the original points. I checked the ignition with a 12 volt timing light this morning and it is firing. I used an old 12 VW Beetle coil I had. VW must use a resistor in their coils as the primary circuit resistance is over 5 Ohms. VW 6 volt and 12 volt coils don't use a external resistor according to their schematics. The 12 volt wire on VW's goes from a fuse directly to the + terminal on coil. The battery I am using is a Tower Hobbies 12 volt 7 ah lead acid torqmaster lc. I have been using that battery for 3 years for starting my electric start Ariens walk behind 21 inch lawn mower.
Thanks for your help and the other ones that have replied.
