Needle valve assembly for the Weber DMSA series 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 in the following sizes:
Weber Part Number: 79507
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.
