Description

OEM Honda/Clone Main Jet – Universal Fit for Stock Carburetors


This OEM main jet is engineered for compatibility with most Honda/Clone carburetors on 196–224?cc engines, including models from Predator SP, Ruixing, Hyuai, and Tillotson PK-1. Ideal for stock rebuilds or mild performance setups, it ensures reliable fuel delivery at wide-open throttle.


?? Fits Most 196–224?cc Engines:

  • Honda?GX200 / Clone?196?cc
  • Tillotson?196 /?212?cc
  • Wildcat?223?cc
  • Ducar?196 /?212 /?224?cc
  • Predator?212 (Hemi & Non-Hemi)
  • Predator?224 Non-Hemi


Jetting Recommendations

  • Stock Exhaust (<?0.850") + Factory Air Box:?# .030–.032
  • Aftermarket Exhaust (>?0.800") + Factory Air Box:?# .032–.036
  • Aftermarket Exhaust + Aftermarket Air Filter:?# .035–.039
  • 196?cc Adult Box-Stock Racing:?# .037–.039

If your carb lacks an idle mixture screw or pilot jet tuning, start with the richest setting above to ensure strong mid-range performance.


Tuning Tips

  • Lean Condition (crackling or breakup at WOT): Go up one jet size.
  • Rich Condition (engine bogs or hits a wall at top-end): Go down one jet size.
  • Confirm ignition timing, valve lash, and compression to rule out non-fuel-related issues.
  • Ensure your coil gap is set correctly, and check fuel system components (tank venting, pump output) before adjusting jet size.

 

Note

Environmental factors (elevation, temperature) and engine modifications (cams, port work) may require fine jetting adjustments. Always tune systematically for best results.
