Well, not really, just sort of an odd question for a marketplace forum. Perhaps you couldn't find the engines forum or the giant scale forum.

Most people take the spring off. Not needed, and it maintains a bit of load against the throttle servo.

Good luck,

Hi

I popped mine off and relocated the spring to a position that had very little tension on it.
By the way the throttle resolution was poor with out the extension arm.

"Market Place Forum" [sm=confused.gif]
Who made this a market place forum?

You may take the spring off, but, by removing the spring you remove all tension from the butterfly rod and that will allow it to vibrate and ware in the carb block. This has been a controversy for some time. I removed them from mine some time ago and have had no problems.

I would leave the spring on.
It doen't cause any problems with the servo or throttle operation.

I always disconnect the throttle spring, don't remove it, just bend the little lip that catches the arm so it doesn't try to close the throttle but still keeps the vertical play out of the bearings.
