Description

EC P15-RK Pro Rebuild Kit for Standard Volume (Single Stack, Gas) Carburetors – Uncaptured


The EC P15-RK Pro Rebuild Kit is engineered for serious racers and professionals in the small engine and karting world. Built from a combination of OEM-grade and performance-enhanced aftermarket components, this kit is designed for durability, reliability, and peak performance under racing conditions.


Why Choose EC Pro Rebuild Kits?

  • Race-Ready Components: Every gasket and part is selected or engineered to outperform typical aftermarket kits. These aren’t cost-cut parts—they're racing-grade materials that hold up to the stress of high-RPM engines and aggressive driving.
  • Complete Rebuild Support: Includes not just the core rebuild parts, but also additional components often missing from other kits—ensuring a thorough and reliable rebuild.
  • DIY-Friendly: Every EC Pro Kit comes with an exclusive exploded-view parts diagram, making it easier to identify components and reassemble your Tillotson carburetor with confidence—ideal for racers doing their own work.


Performance Features

Fast Action Main Diaphragm
This premium diaphragm features our proprietary "wagon wheel" design for better dowel consistency and smoother fulcrum height adjustments. It improves throttle response and metering accuracy—an essential upgrade over standard or OEM diaphragms.

High-Volume Pump Gasket
The included 0.040" high-volume fuel pump diaphragm gasket increases flow rate—critical for maintaining consistent fuel delivery under racing conditions. (Note: May be tech-checked—check your class rules before use.)

Short Gas Inlet Seat (.062")
Includes a short .062" inlet seat, ideal for gas-fueled engines including small block 4-cycles and piston-port 2-cycles. This seat provides superior control and tuning flexibility compared to alky seats with .093" orifices.


Captured vs. Uncaptured: What's the Difference?

This P15-RK kit includes an uncaptured needle and fulcrum arm, a common setup for gas carbs used across various track conditions. Unlike captured systems, the uncaptured needle rests freely beneath the arm, offering excellent fuel modulation and widely preferred by karters and builders alike.


Kit Includes:

  • Fast Action Main Metering Diaphragm
  • Metering Diaphragm Gasket
  • .006" Fuel Pump Diaphragm
  • 0.040" High-Volume Fuel Pump Gasket
  • .375" Welch Plug
  • 1.00" Flange Gasket
  • Uncaptured Viton Inlet Needle

  • Fuel Strainer Cork Gasket
  • High/Low Side Needle O-Ring

FAQ

What carburetors does the EC P15-RK rebuild kit fit?

This kit is designed for Tillotson Standard Volume (Single Stack, Gas) carburetors using an uncaptured needle setup. It specifically fits models like HL-182A, HL-188A, HL-223A, HL-248A, HL-250A, HL-263A, HL-278A, HL-283A, HL-285A, HL-293A, HL-293F, HL-314G, HL-323A, and HL-383A.


What’s the difference between captured and uncaptured needle setups?

An uncaptured setup uses a flat-end fulcrum arm that rests on the needle head. A captured setup uses a forked arm that "captures" a dowel on the needle. Uncaptured designs are common for general karting use and work well on both smooth and rough track conditions.


Does this kit work for alcohol (alky) carburetors?

No. This is a gasoline rebuild kit with a .062" short gas inlet seat. If you're running alcohol, you'll need a different kit—typically one with a .093" high-flow inlet seat and components compatible with methanol.


What makes this kit “Pro” grade?

The EC Pro kits are built using OEM or superior aftermarket parts with a focus on durability and performance in racing conditions. The Fast Action main diaphragm, high-volume pump gasket, and improved material qualitymake it ideal for competitive small engine racing.


Is a pop-off pressure tester required when using this kit?

It's strongly recommended to use a pop-off/leak-down tester and fulcrum arm height gauge to verify that your rebuild is performing correctly. These tools help prevent flooding and ensure proper tuning.


Does the kit include installation instructions?

Each EC Pro Kit includes a carburetor parts diagram and assembly breakdown, not typically found in OEM or aftermarket kits. This helps DIY racers reassemble the carburetor correctly and identify parts.
