First, find the "S" mark on the flywheel, and use a Q-tip to rub some paint onto that spot on the flywheel through the sight hole in the flywheel shroud, if necessary to see it. Next, disconnect the battery and remove the points cover. Gap the points at 0.020" to get the timing in the ballpark. Connect one lead of the ohmmeter to ground, the other to the coil side of the points. Rotate the engine in the direction of normal rotation. When the points are closed, the resistance will be zero, and when they're open, the resistance is infinity. When the points are just beginning to break (in transit from closed to open) the needle on your analog ohmmeter will fluctuate and then go to infinite resistance. I don't know what this looks like on a digital meter, I'd have to try it. I prefer an analog meter because of the response time. Anyway, when the points just begin to break as described above, look for the "S" mark in the sight hole on the flywheel shroud. If the timing is just right, when the points are just beginning to break, the "S" mark will be centered in the window. If it's not centered, adjust the point gap a bit and repeat until you get the "S" mark centered when the points begin to break. Trial and error is probably going to be necessary. After you're all done, make sure the adjustment screw is tight and that the gap does not change when you tighten the adjustment screw. If you don't hold the little tab on the points with a screwdriver tip while you tighten the screw, you'll probably lose your new point gap and it won't run right. Put the cover back on and reconnect the battery. The engine should now start easily and run smoothly.
