I hit a piece of concrete with my trusty old Briggs 3.5 HP Quantum 35 100700; now it won't start. When pulling the starter cord, I feel some resistance, like it's not spinning like it should. Did I shear the flywheel key? Or something worse?

Thanks!:)

Hi gandrew55,
You likely sheared the key but you may have bent the shaft also giving you some resistance. Did you bend the blade?

You could have bent the blade or crankshaft.

I agree with Hi gandrew55.
