Typical symptoms of cracked coils. At least take a look
EDIT: Actually, it sounds like it had suddenly lost spark. Sheared flywheel key? Shorted stop wires/switch?
Interesting that you mention the stop wires. The motor is a manual start now, but it looks like it once had an electric start. I checked my Johnson manual and it said that the ‘ground lead’ should be removed when installing an electric ignition. My motor does not have a ‘ground lead’. Also, the instructions in the manual say to add a ‘white lead (safety switch)’ when installing an electric starter. My motor has one of these.
So, maybe this motor used to have an electric start and now doesn’t? I figured since I was getting spark the stop switch couldn’t be the problem. Maybe not.
Picture below shows what I am talking about.
