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

If you are talking about the stock Mazda RX-7 throttle body, what I did with
the spring was to reverse it on the shaft such that if my cable broke, the
spring would hold the throttle wide open.  I figure I could use either the
ignition or more likely the fuel injector toggle switches to kill the engine
when I needed to.
