If you are referring to the throttle spring on the tx, then you can do 1 of 2 things:
1. cut coils off the throttle spring until you get the correct tension
2. go to your local small parts and bearing shop and purchase another spring
However, if you are referring to the throttle on a gas/nitro car then go to the other thread as stated.
