I would leave the spring in place no mater if I used ny-rod or not. That spring keeps the throttle plate from vibrating ...maybe wearing the fit it shoud have. The pull at the servo is hardly excessive with a long arm on the throttle shaft. I even made a neat little adjustment set-up at servo end. I do not have time right now ...but I could hook up a digital meter in series with the servo & measure Milli-Amp draw as I work the throttle. lots of fun stuff.....lets see ....whats next!
