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.

No fire to spark plug, needs new coil (magneto)
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.

Blew a head gasket
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.
If your new to this, keep nuts and bolts organized, and it goes easy!!

    The right parts on time
    The coil arrived and is installed along with a drive assy. for the Husky Mower. The drive wheel assy is much better than the original! It's great to have this mower which was quite expensive back in 2000 running well again! Thanks R.P. for making it easy. Ordering parts at the local power shops is always a pain in the rear.
