Needle valve assembly for the Weber IDF carburetors.
This is a so-called "Needle Valve Assembly" as it is more than just the "needle".
The assembly, or set, is supplied as seen on the photograph here and consists of a base and a needle.
The base, that is screwed into the top cover, is drilled to a specific size or calibration and it is this that determines the flow of fuel.
The needle, with its typical pointed tip, slides into the base and is equipped with a spring-loaded ball and a bracket which allows it to be hooked onto the float.
The base is engraved with the calibration size.
Available from our stock in the following sizes:
Required quantity per carburettor: 1
This is item number 53 in the drawing.
To order the correct size needle valve for your application, please check your existing needle valve for its markings.
You then need to select the correct size / calibration by selecting it through the drop-down menu marked "Size / Calibration *" just above the "Add to cart" button on this page.
The system will not allow you to order this needle valve without selecting a size.
