WAG Echo 650 

or Echo 660 

I see your looking for a flywheel for it. So you got this one?  Start, run, cut?    What was it doing to need a flywheel?

You may still have problems with the pawls but as far as the starter not engaging on this model of saw is usually worn out body mounts.  Had a couple 660's that would both skip when pull starting. A local shop tried to put a shim behind the flywheel. I told them I thought the mounts where worn out causing to much flex of the starter away from the flywheel. Anyway shim didn't work and of course no refund so I made my own mounts using longer bolts through rubber plugs and it fixed both saws...
