Description

EC P1-DG Pro Rebuild Kit for Standard Volume (Single Stack, Gas) Tillotson Carburetors


The EC P1-DG Pro Rebuild Kit is engineered for serious racers and performance builders who demand reliability, consistency, and throttle precision from their standard volume (single stack, gas) Tillotson-style carburetors.


Designed using OE or higher-grade aftermarket components, this kit goes far beyond basic rebuild options. Each part is carefully selected to ensure durability in high-RPM racing environments, making it ideal for kart racers, minibike tuners, and small engine competitors.


Professional Quality. Race-Proven Performance.

Unlike typical OE or aftermarket kits, the EC P1-DG includes hard-to-find components like the brass fuel strainer screen and fuel screen cork gasket, which are essential for long-term carburetor reliability but are often excluded from other kits.


We also provide an exclusive Tillotson carburetor diagram with each kit—something no other OE or aftermarket rebuild kits include. This detailed reference helps racers and DIY mechanics correctly identify parts and reassemble the carburetor with confidence.


Fast Action Main Diaphragm – Built for Throttle Response

Central to the EC P1-DG Kit is our proprietary Fast Action Main Diaphragm. This high-performance diaphragm features:

  • A more consistent dowel height for accurate fulcrum adjustment
  • A smoother metal finish for longer wear
  • Rapid fuel metering and throttle response under acceleration

The diaphragm’s design improves consistency across the stack, making it a true upgrade over both OE and generic aftermarket alternatives.


High-Volume Fuel Delivery for Racing Applications

Also included is the 0.040" High-Volume Fuel Pump Diaphragm Gasket, a favored tech item in competitive kart racing. Paired with the .006" fuel pump diaphragm, this combination increases fuel pumping volume while maintaining tuning stability.

Note: Always verify compatibility with your class rules and carburetor specs before ordering.

A: Yes! This kit includes the main diaphragm, fuel pump gaskets, brass strainer screen, cork gasket, and even a detailed Tillotson carburetor diagram to guide you during reassembly.


Q5: Is this kit suitable for kart racing and small engine competitions?

A: Absolutely. The EC P1-DG is specifically built for competitive racing environments, providing both performance and reliability for high-output small engine builds.


Q6: What makes EC Pro Kits better than OE or generic kits?

A: EC Pro Kits are designed with racing-first priorities—using better materials, adding critical components often missing in OE kits (like the fuel screen), and including a parts diagram to simplify tuning and reassembly.
