Chain saw ignition timing

My new Craftsman 16" chain saw, model 358.350460, is very difficult to start when cold. It acts like the ignition is too far advanced by snapping the pull start handle from my hand. It appears that the timing is not adjustable and fixed by the flywheel/crankshaft keyway pin. When warmed up, it will restart much easier. I'd appreciate any advice on how to rectify this problem.

 

That is correct that the key is integral to the flywheel. The only clear way to determine if it is sheared is to remove the flywheel. This is certainly a possibility, but not very likely, unless the nut torque was insufficient from the factory or if someone has ever removed the flywheel before. Another area to look at is the starter pulley and the pawls on the flywheel for wear or damage. In other words, perhaps you're not getting a good, full pull...slipping while pulling over. The difficult cold start may be another problem altogether and most likely carburetor related, necessitating a rebuild.

 

If it is indeed new - take it back to sears and have them fix it under warrantty.
