There are a few ways to set the ignition timing on a braker points ignition on a moped. This is the method I prefer. For all Tomos moped, like a35, a3, a55, a52, apn 6, apn 4, 14m,15 slc, 15sl, sl15, slc15. and other Tomos moped Can be used on Puch maxi mopeds too, but take care !!! the rotation is the opposite ( right)!!!. Solifer, Zundapp and Kreidler mopeds also use this kind of ignition.
