That is an excellent mower to own and operate. I love the lack of self propel problems (because there IS no sp).

The coil should be an open to run part number.

For the no spark problem, first thing i would try is pulling the coil and making sure there is no rust on coil where it "meets" the flywheel. Also check the flywheel magnets for rust and clean if needed. The rust buildup can effect getting the proper gap between flywheel and coil.

Reinstall coil and gap with a business card or something similar, if still no spark you can pull the coil again and bake it at about 150 to 200 degrees for 30 to 60 mins and then try it again.

hope this helps!!

Coil number is 683080 or 683215. Either one will work.
