Tecumseh Carburetor Main Nozzle Tube

The Tecumseh carburetor main nozzle tube, also called a main jet nozzle or emulsion tube, is a replacement part for Tecumseh-powered small engine carburetors. It meters fuel from the float bowl into the carburetor venturi, where it mixes with incoming air. That mixing supports smooth starting, steady idle, and consistent power under load.

Key Features:

• Replacement main nozzle tube for Tecumseh small engine carburetors
• Helps deliver consistent fuel metering and a stable air-fuel mixture
• Restores performance lost to a clogged, varnished, or worn nozzle
• Made to match the original equipment design for a proper fit
• Suited to lawn mower, tiller, snow thrower, and other outdoor power equipment engines

A clean, correctly functioning main nozzle tube helps prevent hard starting, surging, rough running, and poor fuel economy. Choose the specific part number that matches your carburetor from the available options.
