Description

13-1592 OEM Tillotson Throttle Shaft & Lever Assembly – Fits HL-Series Carburetors


Restore throttle control and performance with the Tillotson 13-1592 OEM Throttle Shaft and Lever Assembly, designed for select HL-series Tillotson carburetors with a 1.00" throttle bore.


More than just a rotating shaft, this precision-machined component is critical to regulating airflow via the throttle shutter (butterfly). The directional pull and mounting orientation of each throttle shaft are specific to the carburetor’s body design and application, making correct fitment essential.


Because Tillotson carburetors are highly modular, your carburetor may have been previously modified, and the existing throttle shaft may not be original. Always verify bore size and model compatibility before purchasing.
