Ok, I have my shiny new '39 H home and off the trailer. I filed the points, fresh gas, and was able to pull start it to load it and mower.
BUT, the magneto cap was wired 180 out. I got the book in, and took magneto off, verified the drive was at 2:30/8:00. I set the little gears up with the R pointing at the chamfered tooth. Put everything back together, and rotor pointed to 4:00 with #1 cyl at TDC. Checked that 3 times. wired it accordingly with: 42 31
Started it with crank. took several pulls, but no kickback, and it seemed to run smooth. It was getting dark, and was able to see flame from exhaust. (no muffler yet). It didn't run hot, but seemed weak, so I vowed to try again.
Yesterday, I advanced the rotor gear one tooth, (may have been off by that much). Went by the book timing it again. Started MUCH easier. No flame from exhaust, and it seems a good bit stronger.
BUT, it is still wired 42 31 because #1 at TDC looks like the #3 tower is about to fire.
Starts with 4 pulls (2 full choke, 2 half choke at 1/2 throttle. I think I can fine-tune starting and get it down to 2 or 3 pulls.)
One other note: I tried the 7:00-11:00 pull, and either I'm a pansy, or something else is odd. The crank will just roll back w/o tripping impulse if I don't pull it past 12:00. Even my very large step-son can't do it.
I've got the tractor timed for 2 degrees or so ATDC, and it has never attempted to kick back.
Serial # is below 2500.
I'm thinking the problem has to be in the little gears, but I tried as carefully as I could to make the R line up with the notched tooth on the small gear. Anyone seen anything like this?
I'm good with the way the tractor starts and runs, and I'll leave it alone, but it is going to confuse the heck out of anyone just looking at it.

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
