The only way to adjust the timing on those is to move the coil, or re-index the flywheel. The key is moulded into the flywheel. I have seen SEVERAL of those with sheared keys. The nuts don't get tightened enough at the factory. The saw kicks back on compression when you shut it down, and shears the key.
Advancing timing more than a degree or two on saw engines is flirting with trouble. That trick has been tried by lots of guys to cover up bad port work. Those engines do not live long from what I hear.
