This is an insulator assembly includes the insulator, seals, and hardware. It is designed to create the right spacing between the cylinder and carburetor on many blowers and trimmers made by various manufacturers. The insulator assembly also keeps heat from moving between the other components. Over time, the insulator assembly can become damaged or crack. When this occurs, air can reach the engine and create a condition where the engine can't perform at its best. If this happens, the insulator assembly will need to be replaced. Take off the air filter, drain the fuel, and remove the intake assembly. The insulator can be taken off of the engine before the replacement is added. Use mounting screws to fit the insulator to the other components. Reassemble the other parts to use the tool.This insulator assembly is a genuine OEM replacement part sourced directly from the manufacturer. It is sold as an individual part.

These O rings are replacement parts intended for use in a number of gasoline-powered lawn trimmers. The O rings serve as gaskets and are placed at the entry and exit points in the carburetors where gasoline and air are mixed and the expansion powers the trimmer. Though constructed of durable material, periodically the flow of the air/fuel mix or the rush of expanding air will cause damage to occur to the O rings so they become less resilient and the carburetor functions less efficiently. In these cases, users often decide to replace not just the element of the carburetor but the O rings as well. Users may notice problems with the carburetor when they cannot get an adequate adjustment, allowing the trimmer to function smoothly. They may also have trouble getting the trimmers to start at all or run without smoking. To replace the O rings, remove the air filter cover and carburetor. Once the carburetor has been cleaned, and the gasket and filter replaced, add a fresh mix of 40:1 fuel. The trimmer should start immediately. These OEM certified O rings are compatible with Bolens, Troy-Bilt, Yard Machines, and Craftsmen trimmers.

A carburetor gasket is a thin rubber material that provides a seal between two parts. Its primary purpose is to prevent fuel and air leaks. This gasket is installed between the air cleaner and the carburetor. Over time, it can crack and tear due to heat and fuel exposure. When this happens, the carburetor may produce the wrong combustible mixture for the engine. In return, the engine may experience rough idling and flooding. A carburetor gasket replacement is necessary. MTD makes this carburetor gasket replacement. It is manufactured to fit string trimmer, leaf blower and tiller made by MTD, Bolens, Troy-Bilt, and Craftsman. This brand-new carburetor gasket is sold individually.
