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.

This carburetor is a device for supplying a two-cycle engine with a mixture of air and fuel. This part comes pre-assembled and has a plastic choke lever along with a metal body. The primary purpose of a carburetor is to mix the right amount of fuel with air so that the engine runs properly. If enough fuel is not mixed with the air, the engine runs lean and can either stop running or gets damaged. On the other hand, if too much fuel is mixed with air, the engine runs rich, and it either floods, runs poorly, runs very smoky, or wastes fuel. The carburetor is in charge of getting the right mixture. If the carburetor is clogged, the engine will not get enough fuel. It may not start or may run rough. The procedure to replace the carburetor is quick and easy, taking only around 15 minutes, but it is recommended to work in a ventilated area. This carburetor works with outdoor power tools like the trimmer, leaf blower, and tiller. It is compatible with specific products from popular brands like Craftsman, MTD, Murray, and Troy-Bilt.
