Dellorto carburetor needle
Carburetor needle Dellorto A02, type 1403 / 8374. 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.

Carburetor needle
Although it is relatively rare, sometimes you need to change the carburetor needle to fine-tune the carburetor. In most cases, it is sufficient to change the position of the needle to optimize the settings.
The position of the needle mainly affects engine behavior in the partial load range (1/4 to 3/4 throttle).
The thickness of the needle affects the entire rpm range. Thinner needles lead to richer mixture, thicker ones will lean out the mixture.
When adjusting the carburetor, it's a good idea to experiment a bit, preferably ordering a box of main jets (full throttle range), a box of pilot jets (mixture at low rpm) and a box of needles.
