Description

EC P19-RK Pro Rebuild Kit for Tillotson HR Standard Volume (Single Stack, Gas) Carburetors


The EC P19-RK Pro Rebuild Kit is specifically engineered for racers and performance tuners working with Tillotson HR carburetors running standard volume (single stack) fuel pump systems. Built for serious small engine racing, this kit combines OE-grade components with precision aftermarket upgrades for unmatched performance, reliability, and tuning consistency.


Built for the Demands of Racing

Designed with input from professionals, every component in this kit is selected to withstand the rigors of high-RPM operation. Where it matters most—like needle seats and diaphragms—we use components that outperform standard aftermarket kits, delivering better fuel control, durability, and throttle response.


What Sets EC Pro Kits Apart:

  • Fast Action Main Metering Diaphragm
    Our proprietary diaphragm features a precision “wagon wheel” design for consistent dowel height and a smooth metal finish, offering faster throttle response and more precise fulcrum arm tuning.
  • High Volume Fuel Pump Gasket
    The included 0.040" fuel pump diaphragm gasket increases fuel flow—perfect for gas-powered 2-cycle piston ports and 4-cycle small blocks. (Always check your class rules before use.)
  • Gas-Specific Fuel Inlet Seat
    This kit includes the short .062" orifice gas seat, preferred for gasoline applications. (The P5-RK variant uses the larger .093" alky seat.)
  • Captured Needle & Fulcrum Arm Assembly
    Ensures consistent fuel control and lever engagement, especially valuable on smooth racing surfaces.
  • Exclusive Illustrated Parts Diagram
    A full carburetor breakdown is included—exclusive to EC Pro Kits—to help racers reassemble their carburetors with confidence.
