RCEJK -
There is somthing wrong with your setup.
Are you pulling your carb at an angle? You should not be.
Is your carb linkage level?
When your carb is fully open do you have any extra throw in your linkage?
If you do not then you need to put a piece of fuel tubing behind your linkage carrier on your servo. This way if you have a full throttle chassis twist it will absorb the extra movement.
When you are on the brakes fully does your carb return spring fully collapse?
Rubber gromets?
Servo shimmed up?
Hope this helps,
TEX
