2. Ordered new armature magneto (AM) and spark plug boot from eReplacementParts.com
3. Read included directions
4. Put mower on workbench, disconnected spark plug cable, removed top cover and cleaned.
5. Removed spark plug. Removed 2 hex bolts and wire, lifted ... Read more old AMout.
6. Rotated mower flywheel to opposite side per directions, attached wire to new AM, bolted into place per instructions, leaving big space between new AM and flywheel.
7. Again per instructions, rotated mower flywheel so that magnets face AM. Placed 0.010-inch thick card (included with AM) between AM and flywheel.
8. Loosened and re-tightened bolts. Now there is a 0.010-in gap between the AM and flywheel.
9. Reassembled. Put mower on floor and connected spark plug.
10. Gave a mighty pull and mowed my lawn.
