Description

Tillotson 34-195 Captured Inlet Needle – OEM Fuel Control for High-Performance 2-Cycle Carburetors


Precision Fuel Metering for Downward Pump Stack Carburetors

The Tillotson 34-195 Captured Inlet Needle is a genuine OEM part designed to control fuel flow into the metering chamber of Tillotson carburetors, ensuring precise fuel delivery for racing and performance applications. This needle features a captured design, using a dowel pin that is held securely by the fulcrum arm fork. This ensures constant, positive contact between the arm and needle, minimizing bounce and maintaining consistent fuel pressure.


The 34-195 is commonly used in carburetors with downward-facing pump stack plates, typically found on 2-cycle engines, but it may also be used in some 4-cycle setups depending on the carburetor configuration. Its OEM quality guarantees a proper seal and long-term reliability in demanding race conditions.


Key Features:

  • Part Number: 34-195
  • Needle Type: Captured (dowel stem with fulcrum fork contact)
  • Application: 2-cycle engines, some 4-cycle setups
  • Carb Type: Downward pump stack Tillotson carburetors
  • Function: Controls fuel flow into the metering chamber
  • Compatibility: Use only with matching OEM seat and correct configuration


OEM Quality Matters – Avoid Aftermarket Issues

Aftermarket inlet needles and seats are a common source of post-rebuild problems. Poor tolerances often result in improper sealing, causing flooding at idle, erratic performance, and excessive fuel from the high-side circuit. Use a pop-off pressure gauge to ensure the needle and seat seal properly during carburetor setup.


Fitment Note:

Check your carburetor model and specifications before ordering. The 34-195 is designed for use with captured fulcrum arm configurations and downward-facing fuel stack plates.


FAQ

Q1: What is the purpose of the captured inlet needle?
A: It ensures stable contact with the fulcrum arm, allowing accurate and consistent fuel flow into the carburetor’s metering chamber.


Q2: What engines use the 34-195 needle?
A: This needle is designed for Tillotson carburetors with downward-facing pump stacks, typically used on 2-cycle engines, and in some 4-cycle racing applications.


Q3: Is this needle compatible with methanol?
A: The 34-195 is primarily used in gasoline-based systems, but check your engine and carburetor application to confirm compatibility.


Q4: Why are aftermarket inlet needles not recommended?
A: They often don’t seal properly, which can cause fuel leakage, poor idle performance, and flooding—especially on the high side circuit.


Q5: How can I ensure proper installation?
A: Use an OEM seat, confirm needle compatibility, and test pop-off pressure with a pressure gauge to avoid leaks or tuning issues.
