OK I downloaded the manual. I got the flywheel off and there are not broken wires. I got the points set (with feelers as it is not running) I have no spark. Points are opening and closing, keystock is in crank so engine is physically in time. This ran last year and was stored for the winter.

Nothing in the manual about testing the coil as it is the only other thing I can see electrically.

Condensor/capacitor might be bad.
Momentarily disconnect it and see if you get a spark. It might run crappy, but it should at least pop. Don't run for any extended time without the cap. It'll "eat" the point contacts.

Been borrowing one all summer finallly got into it. I need a new coil and will replace condensor as well. Anyone have the part numbers for those two items?

I see listings for 161 and 181 engines which is in the manual with the 91
