Carburetor Needle Dellorto A39 PHVA – PHBN

Dellorto carburetor needleCarburetor needle Dellorto A39. Used for PHVA, PHBN carburetors.

Together with the emulsion  tube, the carburetor needle controls mixture at half-throttle.

The position of the needle is adjusted by the changing the height of the clip. Generally, if the mixture is too lean, the clip on the needle is set one step down, and if the mixture is too rich, it is set one step up.

In addition to carburetor needles, we also carry a wide range of carburetor accessories and spare parts. Since adjusting the carburetor via the needle is not entirely predictable, we recommend this carburetor needle set A2 – A33 to experiment with.
