Description

13-1956 Tillotson HS Throttle Shaft – For Pre-2019 HS Carburetors


Enhance the performance and reliability of your carburetor with the Tillotson 13-1956 Throttle Shaft, engineered specifically for pre-2019 HS-series Tillotson carburetors.


More than just a mounting point for the throttle shutter (butterfly), this throttle shaft is uniquely designed to match the internal geometry and directional pull of specific HS carburetor bodies. The directional pull—whether from the left, right, or alternate angles—helps determine the intended application and function of the carburetor in small engines, chainsaws, and racing applications.


Important Compatibility Note:
This throttle shaft is only compatible with older, pre-2019 Tillotson HS carburetors. Tillotson later reused the "HS" designation for newer carburetor models that do not share components with the original HS series. This part is not compatible with post-2019 HS carburetors.


Product Features:

  • Genuine Tillotson OEM part – Part #13-1956
  • Designed for pre-2019 HS-series carburetors
  • Provides stable and accurate throttle control
  • Precisely machined to fit original HS carburetor bodies
  • Not interchangeable with newer HS models

FAQ

Q1: What carburetors is the 13-1956 Tillotson throttle shaft compatible with?
A: The 13-1956 throttle shaft is compatible only with pre-2019 Tillotson HS-series carburetors. It will not fit newer HS models introduced after 2019, as they use different internal designs.


Q2: Is this a genuine Tillotson OEM part?
A: Yes, the 13-1956 is a genuine OEM Tillotson throttle shaft, built for exact fit and function in older HS-series carburetors.


Q3: How can I tell if my carburetor is a pre-2019 HS model?
A: Check your carburetor's model number and production year. Older HS models typically have different internal designs than the newer HS series (post-2019), and many parts, including the throttle shaft, are not interchangeable.


Q4: What does the throttle shaft do in a Tillotson carburetor?
A: The throttle shaft holds and rotates the throttle shutter (butterfly), controlling airflow through the carburetor. Its direction of pull also indicates specific design and application features of the carburetor.


Q5: Can I use this part on a newer HS Tillotson carburetor?
A: No. While both older and newer models are labeled "HS," they do not share components. This throttle shaft is only for use in older, pre-2019 HS-series carburetors.
