Description

233-706 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit – .062" Long Gas Seat


The 233-706 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit is a high-quality replacement kit designed for Tillotson gas carburetors. This version includes a .062" long gas seat—often used in performance or high-demand applications—along with a captured needle and a 16B-199 copper seat gasket for reliable sealing and smooth fuel delivery.


Key Features:

  • .062" fuel seat orifice – ideal for gas carburetors, providing controlled fuel flow
  • 0.650" seat length – longer than typical short seats; check specs for compatibility
  • Captured inlet needle – ensures constant contact with the fulcrum arm for precise operation
  • Includes copper gasket – ensures a tight, leak-free fit


Technical Specs:

  • Seat Orifice: 0.062"
  • Seat Length: 0.650"
  • Needle Type: Captured
  • Gasket: 16B-199 Copper Seat Gasket


Fitment & Use Notes:

This long gas seat features a smaller orifice than those used in methanol carburetors, making it ideal for gasoline-fueled engines. However, not all gas carburetors require a gas seat—higher displacement or high-RPM engines may need larger orifice sizes to meet fuel demands. Always refer to your carburetor’s model specifications or, preferably, measure the orifice size before installation—especially on blueprinted, modified, or high-performance engines.


The included captured needle is designed for setups where the fuel pump stack is facing downward, keeping the fulcrum arm lever securely engaged for consistent operation.


Kit Includes:

  • One .062" long gas seat (0.650")
  • One captured fuel inlet needle
  • One 16B-199 copper seat gasket


Maintain precise fuel control and peak engine performance with the Tillotson 233-706 Needle, Seat, and Gasket Kit – trusted by tuners, builders, and racing pros.

FAQ

Q1: What is the difference between the 233-706 and 233-707 Tillotson kits?

A: The 233-706 kit features a longer seat (0.650"), while the 233-707 includes a shorter seat (0.535"). Both have a .062" orifice and are intended for gas carburetors. Always measure your existing seat before choosing.


Q2: Is the 233-706 kit compatible with methanol carburetors?

A: No, this kit is designed for gas applications. Methanol carburetors typically require a larger orifice seat due to higher fuel volume requirements.


Q3: What is a “captured” needle?

A: A captured needle is secured by the fulcrum lever fork, ensuring continuous contact during operation. It’s commonly used in carburetors where the fuel pump stack faces downward.


Q4: How do I verify if this seat fits my Tillotson carburetor?

A: Measure your current seat’s length and orifice diameter. This kit includes a .062" orifice and 0.650" length—ideal for certain gas applications but not universal.


Q5: What’s included in the 233-706 kit?

A: The kit contains:

  • One .062" long fuel seat (0.650")
  • One captured fuel inlet needle
