I have a BR600 that has no spark, just bought a new ignition coil and still no spark. I tried different airgaps from .008 up to .014 and nothing changed. The micro switch in the handle ohmed out good so I know it isnt that. I tried it with an adjustable spark tester also. I recently disassembled the whole blower and was using an impact gun to get the fan off the other end of the crankshaft, and I'm wondering if the shock may have damaged something inside the Ignition flywheel. Is there more than just magnets in the flywheel? Thanks for any help.
