Description

PK-3A Tillotson GX200 / Clone / Predator Stock Racing Carburetor


The PK-3A Tillotson Stock Carburetor is a performance-calibrated version of the standard GX200-style carburetor—precision-engineered by Tillotson LTD and EC Carburetors, the global leader in small engine racing fuel systems. Developed to meet the needs of Clone class kart racers, this carb is designed for consistent out-of-the-box performance and compliance with tech inspection rules across multiple racing organizations.


Unlike generic lawn & garden carbs, the PK-3A has been factory blueprinted specifically for 196cc–224cc OHV engines, making it an ideal upgrade for karting, mini bikes, and other racing applications. It’s based on the proven PK-1A layout but with improved casting for better airflow, and enhanced compatibility with Predator 212, Tillotson 212R, Honda GX200, and most Clone class engines.


Key Features:

  • Machined venturi: .6135" ± .001" – optimized for .615" "no-go" rules
  • Progressive emulsion tube for smooth fuel atomization
  • Main jet (stock): .032"
  • Pilot jet (stock): .019"
  • Compatible with stock air boxes and mufflers
  • Tuned specifically for Tillotson 212R but adaptable to many engines


Performance & Tuning Notes:

This carb is intended as a performance base for Clone class and Predator 212 stock racing. It provides outstanding fuel delivery in its stock form for engines limited to around 5500 RPM, such as OTB(Out-of-the-box) or governed classes.

Recommended Jetting for Higher RPM Applications:

  • Mini bikes or open class karts (5500–7000+ RPM)
    • Main jet: .036"–.038"
    • Pilot/Low speed jet: Up to .024"
  • Built Box Stock Clone engines (ported heads, CL-3 cam, 10.8 springs, 32° timing)
    • Main jet: .035"–.038"
    • Pilot jet: .028"–.035"
      Note: Higher fueling volume can cause rough idle or loading up at low RPMs.


Application:

  • Racing Classes: AKRA, Box Stock, Predator 212, Tillotson 212R
  • Engine Compatibility: 196cc, 212cc, 223cc, 224cc OHV engines
  • Best for: Stock-appearing classes, mini bikes, kart racers needing near-blueprinted performance right out of the box
