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?

Return Spring Randy

Answer:

Return Spring Randy,

Yes you do.  In the General Regulations section on page 9 of the 2012 NHRA Rulebook it states “Regardless of class, each car must have a foot throttle incorporating a positive-acting return spring attached directly to the carburetor/injector throttle arm.”
