Well, I put one oring in below the battery box 'cause I dont have a 1/2 inch screw. The servos are still quite a bit off the chassis from the shim, spacer and rubber gromet I have had in. The tray does not flex at all at full throttle or brakes, but it seems like the spring is just to strong. I cut the ballcup and cut a link off of the spring, but now its just altering how much angle the servo horn has to push the carb closed. When closed though, the spring could be compressed about 3mm more (full brake) BUT the servo is buzzing quite a bit. Most likely the spring is just to hard. Ill just try to find a different spring. Thanks for the help so far. Till next weekend (or if the parts come before then)...
