The Piston Position Indicator Tool tells you where the piston is at, in the range near top. Moped engines fire the spark plug when the piston is 1.5 to 2.0mm before top. That’s the moment when the points open, called the ignition timing. When you loosen the points mounting screw, they can shift, and change the ignition timing. Then you have to adjust the “gap” so they open at the correct moment, which is specified in either piston position (mm) or crankshaft angle (degrees). Vespa and Peugeot set to 1.5mm (0.060″) BTDC, Puch, Motobecane, Tomos, Derbi and others, set to 2.0mm (0.080″). Do not confuse piston position with points gap, which is 0.35mm (0.014″) to 0.46mm (0.018″). A wider points gap will cause an earlier (advanced) ignition timing. A smaller points gap causes a later (retarded) ignition timing. Using a timing tool in the spark plug hole is more accurate than any other method. Click to enlarge.
