Todd,
I still have that old worn-out 102, and could probably get it to run with a battery, some starting fluid, and a little work on the ignition. After my teen years, it saw only snow duty for a couple of years, but then we put it back to work mowing. For a couple of years in the early '80s I used it to mow about 3 acres at my Dad's shop, then we took it down to the farm, where I used it for about 13 years to maintain an acre to an acre and a half of lawn. Grandma moved off the farm in '92 into a retirement home, and I moved up there a year later into her house.
By '98 Grandma was still hanging in there, but she died a week after celebrating her 99th birthday. The engine on the Cub was dying too, but the last straw for it as a mower was a disintegrated throwout bearing. I reluctantly pushed it to the back of the shed, and found a funky looking used Simplicity Sunrunner that served my mowing duties for about 9 years. The Sunrunner was a good mower for the obstacle course that was the yard at my grandma's old house.
A couple of years later I found another 10 hp Kohler that I was able to patch up enough to put the Cub back into service moving snow and doing light grading with the snow blade. When I moved out of the old farmhouse to a new house nearby in in '04, I brought a small trailer to store and haul my garbage cans to the main road, and I used the 102 to move the trailer as well. As expected, the patched engine didn't hold up for long, When I first got the engine, the cylinder was already bored .030 over and had .015 taper, and the rod journal was loose. I ground the valves, filed the rod cap, and put new rings on it and said a prayer, and I managed to get about 5 or 6 seasons of snow removal and garbage scow use out of it before the engine refused to start without ether, or fouling the plug within a few minutes. I ended up restoring a 129 a couple years ago to use as my main mower, but that's another story.
Over the last couple of years I've been accumulating the necessary parts to do a proper redo of the old Cub, but in the course of chasing down parts, I found a better restoration candidate than the one I already had, so I've been concentrating on fixing that one up instead.
