Description

LK-125A Up-Pull Linkage Kit – Tillotson HL Single Stack Carburetors


The EC LK-125A Up-Pull Linkage Kit is precision-designed for Tillotson HL Single Stack (Two-Plate) diaphragm carburetors with an up-pull throttle shaft—a common configuration when the fuel inlet is positioned on top of the carburetor. This setup is widely used in high-performance kart racing engines and small engine applications where smooth, direct throttle control is critical.


The LK-125A offers clean and efficient 3/16" throttle cable housing (brake line-style) integration using high-quality, CNC-machined components that hold up to the rigors of competitive racing.


Compatible Carburetors:

The LK-125A fits any Tillotson HL Standard Volume (Single Stack, Gas) diaphragm carburetor with an up-pull throttle shaft, including:

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


Kit Includes:

  • 68A-3A Straight Compression Fitting
    Connects your 3/16" throttle cable housing (pt# 300) for a secure, smooth-routing setup in compact engine spaces.
  • EC-139 Billet Throttle Bracket
    Bolts directly to the pump stack of compatible Tillotson HL carburetors, providing a durable anchor point for the throttle cable guide.
  • (2) 6-32 x 1.125" Socket Cap Screws
    Replaces two factory pump stack bolts. Requires a 7/64" Allen wrench for installation.

  • LK-125A: For Single Stack (Two-Plate) HL carburetors
  • LK-125B: For Double Stack (Three-Plate) HL carburetors

The only difference is the length of the included mounting screws.
