I have been working on a 1965 Evinrude 6 hp 6502 I picked up recently. Had no spark when I brought it home. I polished the points and got spark but the top cylinder started firing quite a bit earlier than the bottom (using my drill to check spark) but would eventually start firing. I put it in the tank and it wouldn't start with the rope, I had to spin it faster with the drill to get it to start. It wouldn't stay running in gear so I did a spark check. Pulled the top and it stopped running. Pulled the bottom, no change. So, I have been back over everything I can think of. I put a new set of condensers in it. Coils look good. I cleaned all the grounds, pulled the plate and checked the wires. The top wire (this is the one that was firing perfectly) had a couple of small cracks in it right at the clamp under the plate but the other looked fine. I put everything back together, checked spark again and lower cylinder still started firing slower and seemed to miss a spark every few revolutions. What should I check? Why would it miss fire like that?
