Armature-magneto 590454

Take plastic cover off then take metal cover off and unplug spark plug wire. Remove both screws that hold the armature then unhook the start/ stop switch wire. Install the new one in the reverse order just make sure the flywheel is clean of rust and oils. And the gap between the armature and the flywheel magnets is right I used a feeler gauge but you can use the cardboard package that the part came in for the gauge.

Removed fan shroud
Remove and replace ignition coil and set clearance at 0.010
New spark plug gapped at 0.025
Fill gas tank and start...

Removed air cover(motor cowl) and starter (pull starter), removed coil from motor reinstalled new coil with piece of paper from coil box as this is adjustment for air gap between the coil and the flywheel tightened down coil plugged in kill wire to coil and reinstalled air and starter items put spark plug boot on end of spark plug clip and plugged it back on to spark plug in motor refiled fuel tank and started the mower up to make sure it starts and runs.
PS the reason for the paper from coil box is to allow the magnet on the fly wheel to pass and create the magnetic field necessary to create the spark that the spark plug uses to fire the fuel in the piston chamber that allows you to mow your lawn.

Removed engine covers, moved gas tank and oil fill to the side. Cleaned magnets on flywheel. R&R magneto cool using business cards to establish the gaps. Reassembled gas tank, oil filler/dip stick, cover, starter recoil. Primed carb, pulled starter rope a few times and it started right up.

1. Removed the engine covering to access the magneto.
2. Removed the old magneto.
3. Attached the new magneto.
4. Adjusted the spacing between the magneto and flywheel..
5. Filled fuel tank with gasoline.
6. Set choke, pulled rope starter a few times and engine started..

I disconnected the fuel tank and set it aside without detaching the fuel line.
Then I removed the blower cover and replaced the armature using a file card for a spacer. Then back together and it started first pull.

Tripped head off, inspected all parts, cleaned carburetor bowl while I had it off the engine.
I checked to make sure head and cylinder surface wasn't warped, de-carboned piston top and head. Re-assembled.
This type of repair is pretty straight forward.
