Description

EC PK-875G CNC Gas Stock Appearing Carburetor Kit


Precision-Machined for Maximum Legal Performance in Stock Appearing Classes

The EC PK stock appearing carburetor represents the pinnacle of legal race carburetor engineering—originally developed by EC Carburetors to comply with Box Stock rules while unlocking the full performance potential of “stock appearing” race engines.

Why the PK Dominates Stock Appearing Racing:

When we designed the first PK-1, we built it using precise CAD data to match box stock regulations. For the PK-1B, we refined that design using real-world production insights, factoring in core shift variations from casting. That allows us to CNC-machine every Tillotson PK to the maximum airflow potential—something no other builder can consistently offer.


Key Features & Engineering Advantages:

  • Precision CNC Bore: Maximum legal flow for stock-appearing classes, machined with exact tolerances.
  • Ultra-Thin Stainless Steel Butterfly: Custom D-shaped design avoids breaching the fuel circuit behind the welch plug and minimizes airflow obstruction around the throttle shaft—stronger and thinner than standard brass butterflies.
  • Epoxied & CNC-Matched Insulator: Bonded and machined to seamlessly match the carburetor body and cylinder head inlet for optimal flow.
  • Dyno-Tested for Gasoline/Race Gas: Tuned for WOT (wide open throttle) performance on gasoline-based fuels. For oxygenated fuels, additional tuning may be required.
  • Precision Jetting Caution: The carburetor is precision-machined—be very cautious when re-jetting. Excess force can damage the emulsion tube or Venturi.

Kit Includes:

  • EC Tillotson PK CNC-Machined Stock Appearing Carburetor
  • Custom CNC-Machined Epoxied Insulator
  • Laser-Cut High-Flow Carburetor Gasket
  • Velocity Stack

Fitment & Application:

  • Designed for use in Stock Appearing Clone Racing Engines
  • Compliant with most Box Stock and Stock Appearing Class Rules
  • Compatible with GX200 / Clone 196cc, Predator 212, Ducar, Tillotson, and similar race-prepped engines

FAQ

Q1: Is this carburetor legal for stock appearing classes?
A: Yes, the PK-875G is engineered to comply with most stock appearing and box stock class rules. Always confirm legality with your sanctioning body or track.


Q2: Will this fit my Predator 212 or Clone engine?
A: Yes, it’s compatible with GX200, 196cc Clones, Predator 212 (Hemi & Non-Hemi), Tillotson, and Ducar small block race engines.


Q3: What kind of fuel is it tuned for?
A: This version is optimized for gasoline and race gas. If you plan to run oxygenated fuel, expect to re-tune for proper air/fuel balance.


Q4: What makes this carburetor different from other stock appearing carbs?
A: It features precision CNC machining, an ultra-thin stainless steel butterfly, and matched insulator—all designed for maximum legal airflow and durability.


Q5: Is it easy to install?
A: Yes. It bolts on like a stock carburetor. Just make sure to follow our installation guide for proper tuning and throttle response:
Installation Instructions


Q6: Can I re-jet this carburetor?
A: Yes, but use extreme care. The floor is very thin due to CNC machining, and excessive force can damage the emulsion tube or Venturi area.


Q7: Is the velocity stack included?
A: Yes, the kit includes the velocity stack, carb, CNC insulator, and gasket—everything needed for performance installation.
