This Linkert high speed needle is made for 1-1/4" throat Model M carburetors used on vintage Harley-Davidson applications.
Fitment: Fits Harley-Davidson WLA models from 1940 through 1952 when equipped with the correct 1-1/4" Linkert Model M carburetor.
The high speed needle is an important fuel-metering component inside the Linkert carb. Once the throttle opens up, the correct needle adjustment plays a major part in getting the fuel mixture right and keeping the motor running the way it should.
If your original needle is worn, bent, damaged, or missing, this is a solid replacement for WLA restorations, rider bikes, and Linkert carburetor rebuilds.
When you are working on an old Harley, the little carb parts matter. The right needle, nozzle, and internal pieces are what make the difference between a carb that just looks right and one that actually works right.
