I don't know the logistics but, when I was a teenager many moons ago my 2 stroke motorcycle was stalling out on acceleration and I took it to my friends house who's Dad was a top mechanic from small engines to airplanes . He pulled the plug, said the gap was to wide, closed it a bit and problem was solved. Since then until now I have had chainsaws come to me like wise gapped like a car, I regapped them .o20, problems solved.
