GEARHEAD OFFSET PERFORMANCE FLYWHEEL KEY FITS ECHO CS-590 CS-600P

broke in two after running for a second Im hoping for a replacement

Not sure I want another but I would love a good timing advance

The advance timing fywheel key the day that I received it, I installed it and as as soon as I cranked up the saw, the key shared into two pieces and did not hold up. The flywheel key is made out of aluminum. I would not recommend buying this product again.

Solid part

It definitely needed a little bit of filing to get the fit, but the saw runs great.
