Needle valve for Solex carburetors. The needle valve is the "heart" of the carburetor and is crucial for a correct fuel mixture. A new needle valve ensures that the float level remains constant, which results in the carburetor running better and more economically.

Fits the following Solex carburetors (among others):

• Solex DDH
• Solex ADDHE

Available sizes:

• 1.30 mm
• 1.60 mm
• 1.80 mm

Important facts regarding needle valves:

• The needle valve wears out over time (the tip becomes uneven) and should therefore be replaced regularly for optimal function.
• It is crucial that the fuel pressure is correct and not too high; otherwise, the needle valve cannot close properly. The maximum recommended fuel pressure is usually 0.25 Bar.
• If you experience problems with fuel pressure, or if the carburetor overflows, we highly recommend installing a fuel pressure gauge in combination with a fuel pressure regulator.
