Forcing the throttles past the open position with a strong wrist force may cause problems in itself with the rigging. We all naturally add a tiny bit of force at time to make sure the throttle is still up against the stops but when I say tiny I mean a tiny bit of force. No where near trying to go past the stop.
I've got experience in 10 different 412EP’s and have come across rigging problems with the throttles but I still never encountered any surging and never tried to force my way past the 100% position.
