Description

EC LK-133 Linkage Kit for Tillotson HL Single Stack Carburetors – Up-Pull Throttle with 2-Phase Arm


Optimize Your Throttle Response for Serious Kart Racing

The EC LK-133 Linkage Kit is a premium throttle linkage system specifically engineered for Tillotson HL Single Stack (Two-Plate) diaphragm carburetors. This high-performance upgrade converts your setup to an up-pull throttle configuration, offering cleaner cable routing and smoother, more precise throttle control—ideal for competitive kart racing and high-performance small engine applications.


Built for Durability & Performance

Crafted from CNC-machined billet aluminum, the LK-133 features robust components designed to handle the rigors of racing. It shares the core design of the trusted LK-125 Kit, but includes a specially upgraded 2-phase throttle arm for enhanced control and improved adjustability on the kart.


Key Features:

  • Compatible with Tillotson HL Single Stack (Two-Plate) carburetors
  • Converts to a precise up-pull throttle system
  • Includes 2-phase billet throttle arm for smoother response
  • Durable, lightweight CNC-machined aluminum construction
  • Engineered by EC Carburetors—a trusted name in kart racing performance


What’s Included in the Kit:

  • 68A-3A Straight Compression Fitting
    Securely connects to your 3/16" throttle cable housing (part #300), ensuring smooth routing in compact engine spaces.
  • EC-125 Billet Throttle Bracket
    Attaches directly to the pump stack of Tillotson HL carburetors, providing a solid, stable mount for your throttle cable guide.
  • LK-131 Billet 2-Phase Throttle Arm
    Clamps onto the carb’s extended throttle shaft, converting it to a precise, up-pull throttle setup with improved control.
  • (2x) 6-32 x 1.125” Socket Cap Screws
    Replace existing pump stack bolts; requires a 7/64" hex key for installation.

FAQ

1. What carburetors is the EC LK-133 Linkage Kit compatible with?

The EC LK-133 is designed specifically for Tillotson HL Single Stack (Two-Plate) diaphragm carburetors commonly used in kart racing and small performance engines.


2. What’s the difference between the LK-133 and the LK-132 Kit?

The LK-133 is for Single Stack (Two-Plate) carburetors, while the LK-132 is made for Double Stack (Three-Plate)setups. The difference lies in the length of mounting hardware and stack compatibility.
