quote Garry in Tampa:
The early soft and gooey ones are what made them ad more hardener that made the later ones crack. . . 😆
My 1950 Fleetwin had those coils that melt and the ran all over the top of the motor. That was a job getting all of that residue off the motor. I converted mine to the modern OMC coils on the old laminations. This is the style that has the push rod to actuate the points. The conversion worked great.
