Sall...welcome to Arboristsite!! I know nothing about your particular saw so I will assume its not that old and has a typical ignition module...when you put it back in, place a feeler guage between the module "legs" and the flywheel.... .010-.012 is what you want....and tighten the module down...that should correct any timing issues you have as long as the flywheel key is in place and not sheared...
