6 volt coil

OK ; we have KB1 with good wiring, rebuilt fuel pump ( Then and Now ) . Had issues while driving at a steady 40/45 mph where the engine would act as though someone was turning off the ignition switch or that the fuel was being chocked off. This would be overcome by depressing the accelerator further and it would clear up and continue running correctly.

Had the carburetor rebuilt and when installed it was worse. Returned and had it redone. The carburetor now seams very good. Still get a stumble and am now looking at intermittent loss of spark from the coil.

I hate to just throw money at it but a coil seams like an inexpensive maybe. WHAT I DON’T KNOW IS IF IT HAS OR NEEDS A RESISTOR.

Thanks

Re: 6 volt coil

Most 6 volt applications with less than 8 cyl use a coil that does not need a resistor. A Standard- Blue streak number would be UC 14/ UC14x Borg/ Warner E1 or E-5.
Most time if it is spark, more throttle will make a miss worse not better, so I don't think that is the problem. I would however take a good look at the vacuum advance set up.

Check your fuel pickup tube. Just cleaned mine on my R110. It acted like it was running out of fuel. There was stuff in the bottom part of the tube.

Re: 6 volt coil

When coils go bad they tend to get too warm to touch .... have a feel next time !!
