Fuel System OverPressure 912IS

Actually, the spring IS a safety measure but the opposite than what you stated. It fails with the throttle open so that you can get to a landing spot. Take the engine off line for the approach.

The cable "bushing" should absolutely rotate freely in the throttle arm. It looks like it either isn't installed correctly, needs a little "work", or it's a poor design.

Since the instructions did not call out a specific torque on the nyloc nut it seems I may have tightened it enough to cause the cable to deform the brass bushing. I loosened the nut 1/8 turn and it now floats freely. Fixed.

Will check mine as well. It could simply be over torqued.

Thanks for all the help and advice everyone. Hopefully this is the answer.

That's better! As per Rotax, the throttle and choke cable connections should be tightened 8 to 10 in.-lbs.

Thanks John. I guess I overlooked the Rotax manual. It is odd to me that they use a nylock nut on an engine component.
