Carter AFB Carburetor Idle Mixture Screw Pair – 10-32 X 1.452 With Springs (Type A)

Got a Carter AFB carburetor that’s running a little rough at idle?

Might be time to swap in fresh mixture screws.

This pair from NFS includes two screws and the springs you need—both are 10-32 thread, 1.452 inches long, and made to fit Type A setups.

Made right here in the United States, they're solid replacements for worn or missing screws that can throw off your air-fuel mix at idle.

If you’re tuning for better throttle response or just trying to get that engine to purr, these are a simple fix.

They thread in smooth and let you dial in the idle mixture just the way you want.

Great for rebuilds, restorations, or just fine-tuning an existing carb.

The included springs help hold adjustment so your settings stay put once you’ve got it dialed in.

Whether you're working on a classic car, hot rod, or anything else with a Carter AFB, these screws are made to fit and last.

NFS includes the MPN 1629 for reference, so you know you're getting the right part.

Small part, big difference in how your engine idles and transitions off-idle.

Good stuff for anyone who likes their engine running crisp.
