Description

Inlet Needle Valve Spring for Honda GX200 & Clone Carburetors – Fuel Control Support Spring


The Inlet Needle Valve Spring applies consistent tension to the fuel inlet needle, ensuring it remains securely in contact with the carburetor float. As the float rises and falls with the fuel level, this spring helps the needle open and close precisely—regulating fuel flow into the float bowl.


Even though it’s a small component, a worn or weak needle spring can cause tuning inconsistencies, fuel overflow, or lean running conditions. Replacing this spring is a simple but critical step when rebuilding your carburetor for optimal performance.


Key Functions:

  • Maintains proper pressure between float and inlet needle
  • Supports smooth fuel metering at all RPM ranges
  • Ideal for performance tuning and carburetor maintenance


Compatible Carburetors:

This inlet needle spring fits a wide range of popular clone-style stock carburetors, including:

  • Tillotson PK-1
  • Huayi
  • Ruixing
  • SP Clone-style carburetors


Fits Small Block Engines:

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


Whether you're rebuilding your carb or troubleshooting fuel delivery issues, this needle valve spring is a must-have part for reliable performance in your GX200 or clone engine.
