I am thinking the starter switch might be bad also. Mostly I think I have the wiring wrong.

Should have the same starter switch. Is the wiring on the switch the same as yours

Customer: replied 4 months ago.
not at all the same. it has 2 switches and a starter button.
Expert:  Bradley Martin replied 4 months ago.

Ok I will opt out that is the only schematic I can come up with.

Expert:  Curtis B. replied 4 months ago.

See section 8 for the wiring. Link above! You have engine cranking. but no spark?

Expert:  Curtis B. replied 4 months ago.

With two switches and a starter button, your machine is not factory setup, so there will be no diagram that will match!
