Bartolone Racing Carburetor Needle Clamp Kit

Tired of your carb needles vibrating out of tune?  Bartolone Racing has the answer!  Our new Carb needle clamp kit was designed to keep your needle screw adjustments in place with our new needle clamp kit.  The clamp securely holds new extended easy-to-adjust high/low speed adjustment screws in place while still allowing easy adjustments.  The needle adjustment screws are held in place with Teflon tipped set screws.  The kits will fit on all RC based carbs 603, 661, 771, 813, 990, etc.  

Note: This clamp will NOT work with your stock adjustment needles, unless you have a WT-257 carburetor. Extended adjustment needles must be used for everything else, these are sold separately (Part numbers av521b & av521c)
