A mouse ate the spark plug wire off the magneto

All I had to do was remove the old Magneto ( which was just two screws) then install the new magneto, it came with easy to understand instructions and a spacer for getting the right gap between the magneto and the flywheel magnets . Very simple . The engine started right up as if it was brand new.

The armature magneto was out in my old mower. This mower is close to 20 years old and it has an 11 1/2 horse B&S motor. The engine would run until it got hot, initially, and then it would shut down un

Disconnect the battery
Remove the engine cover
Remove two screws that hold the armature magneto in place.
Remove the stop switch wire

Spin the flywheel so that the magnets are 180 degrees from the armature magneto.
Screw the new armature magneto on, making sure that the side that says "cylinder" is facing down. Loosely tighten the screws enough so that they stay in, but don't hold the armature magneto down. It should move in the groves.
Use the included feeler gauge to correctly gap the spacing between the armature magneto and the flywheel magnets.
Spin the flywheel back so that the magnets pull the armature magneto into position. The card feeler gauge will create the right gap. Tighten the screws.
Turn the flywheel some more and the card will come out.
Measure the sparkplug wire and cut it to the right length. Strip the wire and use the included tip to make your plug wire the right length. Crimp the tip brackets down with plyers.
Pull the boot off your old sparkplugs wire or install a new boot.
Put the boot back over the spark plug
Install the new stop switch wire, or just use the old one, if its in good condition.
Put the engine cover back on.
Reconnect the battery.
