233-707 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit – .062" Short Gas Seat

  • 0.535" seat length – ensure compatibility by measuring your existing seat
  • Captured fuel inlet needle – maintains constant contact with the fulcrum arm lever, designed for carburetors with a downward-facing fuel pump stack
  • Includes copper gasket – ensures a proper seal and leak-free installation

Compatibility Note:

This short gas seat is commonly used in gas-powered engines, but not all gas carburetors require a "gas seat." Larger displacement or high-RPM engines may need a larger orifice. Always verify your carburetor specifications or measure the orifice before installing to ensure proper fit and performance—especially on blueprinted or modified carburetors.


Optimize your engine’s fuel delivery with the 233-707 Tillotson Fuel Inlet Needle, Seat, and Gasket Kit – trusted by performance tuners and DIY enthusiasts alike.

FAQ

Q1: What carburetors is the 233-707 Tillotson Kit compatible with?

A: The 233-707 kit is designed for Tillotson gas carburetors using a .062" short gas seat. Always check your carburetor model or orifice size before installation to ensure compatibility, especially with modified or blueprinted engines.


Q2: What does the "captured needle" design mean?

A: A captured needle is held in constant contact with the fulcrum arm, improving fuel control and performance. It's especially useful in carburetors with downward-facing fuel pump stacks.


Q3: Can this kit be used in methanol carburetors?

A: No. The .062" orifice in this kit is too small for methanol carburetors, which typically require larger fuel seat openings. This kit is best suited for gas applications.


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

A: Measure both the seat length and orifice size of your existing part. The 233-707 kit includes a seat that is 0.535" long with a 0.062" orifice.


Q5: What’s included in the 233-707 kit?

A: The kit includes:

  • One .062" short gas seat
  • One captured fuel inlet needle
  • One 16B-199 copper seat gasket
