Description

LK-135 Up-Pull Linkage Kit – Tillotson HL Single Stack Carburetors


The EC LK-135 Up-Pull Linkage Kit is precision-engineered for Tillotson HL Single Stack (Two-Plate) diaphragm carburetors with an up-pull throttle shaft. This configuration is typically used when the carburetor is mounted with the fuel inlet facing upward, such as in high-performance OHV kart racing engines.


Designed to deliver smooth, reliable throttle control, the LK-135 kit provides clean cable routing and includes all the essential components to install a 3/16" throttle cable housing (brake line style) to your carburetor setup.


Compatible Carburetors:

The LK-135 Linkage Kit fits any Tillotson HL Standard Volume (Single Stack, Gas) diaphragm carburetor with an up-pull throttle shaft, including but not limited to:

  • Tillotson HL-334WX
  • Tillotson HL-334WXG
  • Tillotson HL-304WXG
  • Any HL-series carburetor with a single pump stack and up-pull shaft configuration


Kit Includes:

  • LK-90A 90° Throttle Cable Guide
    Allows for clean routing of your 3/16" throttle cable housing (part #300) for smooth cable action in tight engine bays.
  • EC-139 Billet Throttle Bracket
    Attaches directly to the pump stack of compatible Tillotson HL carburetors, securing the cable guide firmly in place.
  • (2x) 6-32 x 1.125" Socket Cap Screws
    Replaces two existing stack bolts on your carburetor. Installs with a 7/64" Allen wrench.

  • LK-135: For Single Stack (Two-Plate) HL carburetors

  • Designed for up-pull throttle shaft configurations
  • CNC-machined billet aluminum components
  • Clean and professional throttle cable routing
