Thanks, Fred for the advice on timing my Tomos A3 engine. I use a variation of your method. Instead of the coat hanger, I made a mark on the engine housing at TDC and a mark on the flywheel at TDC. I then measured and made the F mark at 3/4 inch as you suggested. Then, I used an ohm meter to set the points to open at the F mark. I did this so I would not have to start the engine every time to check it with the timing light. After I set it with the meter, I did start it and the timing light showed the timing to be correct. You're a genius!
Your help is greatly appreciated as it is much more fun to ride the bike now with it running correctly. If you ever come to Texas, I 'll buy you a cold one.
