i believe your correct on the gears. carb setting to start with, main jet 2 1/2 turns out. idle mixture 1 1/2 turn out. this screw is out for lean and in for rich. have mag bolted to base. get #1 on compression. line up timing mark to TDC. raise breaker housing to retard spark and remove it.lift timing hook to make impuse coupling in operatable.remove dist cap.rotate mag by coupling clockwise as from coupling end. rotate till the brush is coming into alignment with cap terminal #1.just as pionts are opening you are now in time. you can put a piece of paper between points to feel when they open. just as paper pulls out you are timed. without moving a thing put the 2 bolts in the coupling where they line up directly across from each other. replace cap and cover. to check yourself crank engine over on #1 compression and check points , just as they are opening the timing marks should be in line. release timing hook and start tractor. as for compression i would say 80-90 psi.it will run good.
