Hi Pau13z,
Sounds like you may have stretched or bent the crank. I did the same thing when removing the pulley from a tilt a cut with a dead Powertorque. Not sure how it happens, but I could only move the piston so far each way once I had the pulley off. I was told about this by a bloke at a mower shop I visit from time to time. Still have that motor sitting around, I haven’t bothered to inspect it any further yet.
Cheers,
John
