My Husqvarna 357xp refused to restart when fully heated. When I thought of getting the plug out before it cooled down again, I found there was no spark. I diagnosed a faulty coil and ordered an aftermarket part listed as suitable for my saw. Following the instructions in the workshop manual, I set the gap on the lower two metal "pegs" that face the magnets. However, this left the top peg with a huge gap and I couldn't get a spark. The old coil was a Swedish made part (SEM) and all three pegs had more or less the same gap once the lower two were set. It was marked 544 04 70-03. Husqvarna say the currently available part that should fit my saw is numbered 544 04 70-01. I got another aftermarket part that was supposed to be compatible with that number, but it was identical to the first one I got and had the same problem. Rang Husqvarna again. All they could advise was to fit a genuine part. I may have to do that, but reluctant, due to cost.
Can anyone tell me if the genuine OEM part 544 04 70-01 places all three pegs of the coil the same distance from the magnets, or does the gap need to be set in a different way?
