verify that you have voltage to the coils first, next look at the plug wires, and reset the gap on the points making sure they are clean, prefer new points and condensors

Assuming that you have followed the advice above and checked that the voltage across the Coil(s) input is no less than say 0.5 Vdc of the voltage directly across the battery then try the following:

Swap the two coils. If the symptom follows the coil then be prepared to replace the coil... preferably with a new coil (don't ask).

If the symptom does not follow a coil then it may be a trigger (Points, Condenser) fault. Swap the Points.

If the problem follows the Points be prepared to replace with new Points.

If the symptom does not follow the Points then swap the Condensers... you get the idea from here.

Best of success,
Bill

thanks for the response. any input on how to set the points ..that is new to me...thanks
