Re: old johnson no spark

I would start with the points and condensor. Also what condition are the coils in? Are they all cracked and damaged?

And compression, while you're at it. Best to find out now that it is bad, than after you pour money into it.

That $40.00 could be awful expensive.

Make sure all your connections are clean and good. Make sure your battery is a good battery and fully charged. If this dosnt work then the starter may need to be rebuilt or replaced.
