Throttle/Break Servo

[Buster0825]

I have a Futaba 3004 for my throttle/break servo. When I apply the break on the transmitter, it also is closing the carb on the engine. From what I am seeing the break linkage is on the bottom part of the servo and the throttle linkage is on the top and from my understanding when you apply the break the throttle should not close the carb, but on mine it does. Does anyone have any idea on why this is happening? Any help would be greatly appreciated. Thank you in advance for your help.

Thanks!
John

Check your idle screw. the carb slide will sit on that screw when you are off throttle or hit the brakes.

I second that advice

mine does the same thing on the servos. i think it is normal. adjust you're idle if the truck is stalling when brakes are applied
