Walbro Gas valve shaft steel ZN0078/20

If an engine runs unevenly at idle and causes problems with carburetor adjustment, this may be due to a worn throttle valve shaft. These are normally made of brass and wear out quickly, with this stainles steel 304 variant, and certainly in combination with a bearing-mounted carburetor, those problems are solved.

We also have carburetors in our range with bearings on both sides of the shaft, and you can opt for a variant with this steel shaft. These never wear out and always ensure a smooth operating throttle that does not falter or stick.

Equipped with an additional control lever where the throttle rod has three positions for extra quick response and a better working angle.
