Reply To: 1937 Evinrude fisherman 4.4 hp spark issue

My two cents…

1. Compression of 70-80 psi is not low. It’s actually quite high for that motor.
2. The replacement coils look quite old. I wouldn’t trust them even if they test good on the bench.
3. The original condensers are usually bad or failing on those motors. I think they are .1 or .12 mfd. You’d have to look it up.
4. I would use the condensers that are matched to the replacement coils.
5. Unless the copper wire in the high tension lead is bare and arcing to the flywheel it can’t be a source of lost spark.

Good luck with it. It will be a good runner once it’s sorted out.
