Final Super A timing

I hope. Thanks to all who helped me through. I overhauled my Super A engine. Complete rebuild, bearings, oil pump repair, 3.25 diameter pistons. Finally got it to run. The first time I started it, no oil pressure, which necessitated removing the front axle, steering mechanism and governor, and replacing a oil galley plug I left out (after looking right at the hole before I installed the cam and cam gear). In the process I found the governor a little hard to get back in, seemed to be hitting something. So, I removed the distributer and distributer drive, which run off the governor gear. Then I was able to align the marks on the governor gear and cam gear. Then I replaced the distributer drive and distributer. I then put #1 on the compression stroke and lined up the mark on the flywheel with the one on the cover in front of it. Ready to start. The engine would turn about 1 revolution and quit. Obviously out of time. Explanation: The marks on the cam gear/crank gear and the ones on the cam gear/governor gear are 180 degrees apart, in a straight line from the crank gear to the governor gear. But they are NOT exactly inline when the flywheel marks are lined up. What I did when I installed the governor was to match the marks on the cam and governor gear, then set #1 on the compression stroke, align the mark on the fly wheel and install the distributer drive. WRONG! When I matched up the mark on the flywheel, I slightly moved the marks of the governor gear and cam. Still in mesh but they had moved. When I lined up the flywheel mark, I moved the distributer drive out of time. So I removed the distributer drive, THEN aligned the flywheel mark and installed the drive, after, not before I aligned the flywheel. Silly mistake, but easy to do when I was brain dead. The distributer was then installed in the drive with the rotor pointed to #1 terminal on the cap, and timed with the spark between the coil wire and nut on the distributer. The starter could then keep the engine rotating but it did not start. I advanced the distributer slightly, the engine started, and I smoothed it out by timing by ear. Possibly I could have started it by rotating the distributer without removing and replacing the drive, but at that time I was not sure what was going on. So, after 16 months and a total disassembly/reassembly of the entire tractor, it runs. More in the next post.
 
Congratulations. Putting a timing belt on a Subaru with 7 or so pulleys to drape a cog belt over under and around, while the cams do not stay in the correct location because the followers move the gears is also a pain. One tooth off is a non runner. Jim
