I am in need of a crankshaft for a Jonsered 670 Super II. I have a Husqvarna 66 parts saw and I know a lot of the parts will interchange. Are the crankshafts the same?
Im pretty sure they are the same except may be a fine or coarse thread clutch. Also you could have a difference between 2 piece ignition or 1 piece. The flywheel keys are in different marks. I have 3 and all take different flywheels. Good luck great saw.
