Tecumseh OEM Carburetor Needle Seat 631021

This is a genuine Tecumseh OEM carburetor needle seat, part number 631021, manufactured to original Tecumseh factory specifications.

The needle seat works with the float needle to regulate fuel flow into the carburetor bowl. A worn, hardened, or damaged seat can cause flooding, fuel leaks, rich running, or hard starting. Installing a true OEM Tecumseh needle seat restores proper sealing, correct fuel level, and reliable carburetor performance—something aftermarket seats often fail to achieve due to incorrect material or dimensions.

Ideal for carburetor rebuilds, routine maintenance, and engine restorations, this OEM seat is commonly used across a wide range of Tecumseh carburetors.
