If on a moped , there are risks measuring, checking and setting the ignition timing do with a strobe. But keep in mind that a good strobe – a thing not cheap, to the mopedist not pay off due to extremely rare use. Before check warm up the engine well.
Connect a stroboscope according to the instructions attached to it. Two power wires connect to the mains moped, and the induction wire to the spark plug. At the moment of occurrence of the spark at the spark strobe light will give bright light. Point it at measuring risks. If they are in their places relative to each other, so the ignition is exposed correctly. The coincidence of risk should be absolute, or close to that.
If the risk of timing clearly do not match or are not visible at all, the ignition needs adjusting. The method of adjustment of the ignition timing is different for mopeds from different manufacturers. So be sure to read the manual. Measuring risks looking at the flywheel generator and the flywheel housing. When performing work, observe the rules and security measures.
Please note one important point – the ignition timing is determined only when the engine is at certain RPMs. Therefore, the strobe shall be equipped with a speed sensor of the crankshaft. If this parameter is not specified, then setting the ignition spend at idle, making sure that they conform to the norm.
Also be sure to read the instructions for use of the strobe light. This is due to the fact that many manufacturers of these devices does not recommend or prohibit them to connect power to the electrical moped. During the flash lamp of the strobe there is a jump in the load on the power supply of the device, which leads to distorted readings when checking the ignition timing.
