Tecumseh 640172 Lawn Mower Carburetor

The Tecumseh 640172 Engine Carburetor is a combustion power unit that regulates the ratio of fuel and air that enters the intake system to ensure efficient engine performance. The venturi pulls gasoline from calibrated passages forming a fine air mixture before it enters the combustion chamber. The internal circuits are designed to regulate the delivery as operating conditions vary ensuring accurate mixture formation in each delivery cycle. The balanced fuel preparation enables responsive performance, efficient energy conversion, stable operating features, consistent output and smooth mechanical function in normal equipment applications.
