This carburetor insulator is a genuine MTD replacement part for appliances with small engines, such as lawn mowers, lawn tractors, lawn trimmers, snowblowers, chipper shredders, tillers, and leaf blowers. The function of a carburetor insulator in a small engine appliance is to maintain a lower temperature for a running engine and to keep that heat away from the carburetor, the purpose of which is to mix the air and fuel in order to start the engine. A functioning carburetor insulator will prevent the engine from overheating.A broken or non-functioning carburetor insulator will likely not prevent the engine from operating, but it might slow down its power or reduce its fuel economy due to compensation from overheating. An engine with a damaged carburetor insulator might take in more fuel than usual or allow in unmetered air. An unmetered air leak can cause damage to the engine in the short-term so if there appears to be visible damage to the carburetor insulator, it should be replaced as soon as possible.This carburetor insulator is compatible with the following brands: MTD, Cub Cadet, Yard Machines, and Craftsman.

Gasoline may drip from the float bowl because of an O-ring that won't seal or seat evenly all around, or one that has become brittle over time.
