Re: 15 Evinrude 1975 no Spark Driver coil ?

[frankr]

Driver coil’s laminated core ends should be flush with the machined edges of the posts it sits on. Tool is not a necessity, just a convenience. If it is set too close, it will drag on the magnets, too far away, will cause weak or no spark depending on how much too far.

I hesitate to comment on the resistance reading. Not enough experience with keeping up with the possible changes.
