Question:
When I went to run the Friday Night Test & Tune at my local NHRA track the tech official said I needed to have a return spring on my carburetor. I have one on my gas pedal in the driver’s compartment. Do I still need one under the hood?
Answer:
Yes you do. Per the 2019 NHRA Rulebook section 21 page 10 it reads “Regardless of class, each car must have a foot throttle incorporating a positive-acting return spring attached directly to the carburetor/injector throttle arm.”
