I receintly removed the spring from my butterfly valve on the throttle body

thinking that it won't be needed in the aircraft.  Then I realized that
the spring might be useful in preventing flutter of the

butterfly valve.

Does anyone have any experience or advise on the matter?

Thanks,
Dave Leonard

I removed the springs that hold the throttle closed. I am going to put a 
spring on that holds the throttle open so that if I have a failure of 
the throttle cable, the engine will not shut down.
