IIRC timing slips when the key gives from insufficient torque on the nut holding the flywheel on to the crankshft taper. New key to realign flywheel solvent clean inner and outer taper of any slippery stuff line up key & keyway torque fly wheel nut to spec. should correct timingI looked at the saw again today. I narrowed it down to the timing problem. The decomp was weak, so I swapped it out with a better one from a parts saw. It still popped right away though when in run. When the switch was in off or when the spark plug wire was disconnected the saw cranked normally. This saw is stock. So how did the timing get off and how do I retard it?
