Have a 350 with a supposed bad coil. Havent tested it, as the saw needs a little compression help, but assuming the owner goes for the plan of swapping in a 353 Meteor piston kit, the coil could be the next issue. I have access to a couple of 55s that are in pieces with destroyed p&c. All seem to have coils intact. They seem similar, though I havent measured. Does anyone know if the 55 coil will work on the 350?
