Description

Tillotson 34-216 Captured Viton Inlet Needle – OEM Fuel Control for 2-Cycle Engines


Precision Fuel Metering with Superior Sealing for High-Performance Carburetors

The Tillotson 34-216 Captured Viton Inlet Needle is a genuine OEM replacement part engineered for Tillotson carburetors—specifically those with downward-facing pump stack plates, most commonly found on 2-cycle racing engines.


This inlet needle features a captured design with a dowel stem that is securely held by the fulcrum arm, maintaining continuous contact during operation. What sets this needle apart is its Viton tip, offering enhanced sealing, chemical resistance, and longer durability compared to standard rubber-tipped needles.


It ensures consistent fuel regulation under racing conditions, reducing the risk of flooding or poor throttle response. The Viton material is ideal for engines running on gasoline or methanol, delivering reliable performance even in high-vibration or high-temperature environments.


Key Features:

  • Part Number: 34-216
  • Needle Type: Captured inlet needle with Viton tip
  • Material: Viton (for improved fuel resistance and sealing)
  • Best For: 2-cycle engines with downward-facing pump stacks
  • Fuel Compatibility: Gasoline and methanol
  • Application: Tillotson racing carburetors


Don’t Risk Engine Performance with Inferior Aftermarket Parts

Poor-quality aftermarket inlet needles are one of the most common causes of fuel system failures after a carburetor rebuild. These parts often fail to seal properly—especially at low RPM—leading to flooding, erratic idle, and performance loss. Always use OEM parts and confirm pop-off pressure during installation with a pressure gauge.


Fitment Note:

Verify your Tillotson carburetor model and setup before ordering. The 34-216 needle is designed for use in captured-style fulcrum arms and downward-mounted fuel stack configurations.

FAQ

Q1: What is a captured inlet needle?
A: It’s a needle held in place by the fulcrum arm using a dowel or stem. It ensures constant contact for stable fuel metering.


Q2: What’s the benefit of a Viton tip?
A: Viton provides superior sealing, chemical resistance, and durability in high-temp and methanol environments.


Q3: Which engines or carburetors use this needle?
A: It's designed for 2-cycle Tillotson carburetors with downward pump stacks. Check your model before ordering.


Q4: Is it compatible with methanol fuel?
A: Yes. Viton-tipped needles are ideal for both methanol and gasoline applications.


Q5: Why avoid aftermarket inlet needles?
A: Non-OEM parts often fail to seal, causing performance issues like flooding or erratic idle. Always test pop-off pressure after installation.
