Straight forward procedure. Seal was on PTO end, accessed without need to pull engine. shaft was not tapered so no need for a pulley puller. Sealed nicely - no leaks. Use oil to make new seal slip on evenly; do not seat all the way down, just enough to come flush with surface of crankcase.

Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Carb cleaner (dip and spray), small nylon scrub brush.
1) Removed cowl from mower for access to carburetor. Removed air cleaner.
2) Removed and disassembled carburetor paying attention to how throttle and governor linkages are hooked up. (A picture taken with phone is a handy reference for re-assembly.)
3) Cleaned carburetor as much as possible with spray carb cleaner, brush and shop air.
4) Placed metal parts of carb in dip basket, soaked in gallon of carb cleaner overnight to remove residue.
5) Reassembled carburetor using parts from repair kit and bowl replacement kit.

(Replacement solenoid is $70, a $3 on/off valve in the fuel line performs the same function.
6) Cleaned all traces of old gasket from engine block, installed carb using new gasket.
7) Cleaned gas tank, replaced old fuel line and fuel filter. Installed in-line fuel shut off valve.
8) Installed air cleaner assembly, replaced old air filter & pre-filter.
9) Checked oil level, added fuel, and started mower.
10) Ran mower for a few minutes to bring oil up to operating temp. Shut off, drained oil, replaced oil filter and filled with fresh oil.
11) Started mower, let run for a few minutes to check for leaks, shut off fuel flow to carb and let run till motor dies from lack of fuel.
