Description

RuiXing Carburetor Emulsion Tube – OEM Replacement for 196cc GX200 Clone and More


The RuiXing Carburetor Emulsion Tube plays a critical role in mixing air and fuel inside the carburetor, precisely controlling the air-fuel ratio for optimal engine performance. As airspeed and pressure fluctuate with throttle movement and engine RPMs, the emulsion tube regulates this mixture to ensure smooth acceleration and efficient combustion.


This is an OEM replacement stock RuiXing emulsion tube designed for 196cc (6.5 HP) GX200 clone engines and compatible with most clone carburetors, including Ruixing and SP carburetors commonly found on:

  • Honda GX200
  • Ducar 196
  • Ducar/Tillotson 212E
  • Predator 212
  • BSP 196 and 212 engines

Note: The Tillotson PK-1 and Huayi carburetors require different emulsion tubes.
