It should be understood that ignition alone, on imported direct-powered chainsaws, cannot go astray by itself. The number one issue with coils it they expand with heat and break down and normally fire until they get hot. you can not completely unscrew the candle, as this can lead to faster rotation of the flywheel, which is not the correct mode of operation of the engine; it is necessary to place it at a distance that corresponds to the compression model and the dielectric properties of the fuel mixture, therefore this parameter can be viewed in the instructions (a value of 6-7 mm is averaged). Another argument against cam ignition is a larger size and more weight than electronic (this comparison is relevant for modern gearless saws). I bring the frames for viewing from this video below. If the light does not flash inside the tool, the ignition coil needs replacing. A completely faulty ignition coil can often keep the vehicle, especially a 4 cylinder vehicle, from running at all. This same test (either side of primary to ground) on a known good module (Jonsey 2050) reads 215 ohms. On the first Urals with electronic ignition, as far as I remember, the electronic board was filled with mica (epoxy), which, in case of repair, was melted and the board was removed. An example of a known good primary coil … If the probe is missing, then it can be successfully replaced with a fragment from a plastic bottle from under the juice / beer. This is how the ignition coil looks in a half-sawed module, On the other side of the coil there is an electronic board, intensively filled with sealant.
