Tecumseh 632745 Main Tube Nozzle

Product Description

The TECUMSEH 632745 is a main tube nozzle designed for use in small engine carburetor assemblies. This component controls the metered flow of fuel from the carburetor body into the venturi, playing a direct role in air-fuel mixture delivery during normal engine operation. It is a manufacturer-sourced replacement part used by small engine technicians and equipment service professionals working on Tecumseh-powered lawn and garden equipment.

This main tube nozzle fits within the fuel delivery circuit of Tecumseh carburetors commonly found in walk-behind lawn mowers, snow throwers, tillers, and other outdoor power equipment powered by Tecumseh small engines. It is typically replaced during carburetor rebuilds or when fuel delivery issues are traced to a worn, clogged, or damaged nozzle tube.
