Adventures in Lawn Mowing

The mighty five horsepower, air cooled, gasoline fueled, side valve, single cylinder, four stroke, centrifugally governed, cast iron barreled, aluminum headed engine roared back to life!!!

And I was able to finish mowing my modest little lot, hopefully for the last time this year.

As stated, I used my 'product improved' cylinder head, sanded/lapped smooth and straight (over 1200 strokes on 220 grit wet-or-dry) and the 'new' style head gasket. I also switched from the stock seven head bolts (five bolts & two studs with the 'product improved' head) to seven studs and SAE flanged nuts w/stock [thick] washers (called "worshers" in some states)

and re-torqued after running for a short time.

I checked with the old timer who ran the Cadet Cub repair shop and after confirming I had the 'old style' 5hp Kohler engine, recommended torquing to spec and then running "for about an hour" and then letting it cool and re-torque it. The gas tank mounts right over the head so I had to jig-rig a 2x4 and bungee cords to hold the tank away from the head so I could see if it came loose or some other malfunction. I was surprised that the cooled head took about a half turn to each nut to re-torque.

So now it's done and we'll see next Spring if it starts and I mow again or buy a new mower. I'm sort of hoping it won't so I can buy one of the orange compact zero-turn tiller-steer mowers that my neighbors seem to have so much fun with.

Either that, or stuff a 4-cylinder 1974 Honda motorcycle engine in the Cadet and see how long that lasts.
