This particular air cleaner filter is made for gasoline-powered trimmers. If any piece of lawn equipment kicks up more dust and particulate than a lawn mower, it is a trimmer. Trimmer line, unlike a mower, does not maintain a constant angle. Because trimmers are also frequently used as edgers, they fill the air with dust and debris. While air cleaner filters are made of durable material, they eventually become clogged with yard waste to the point that they simply cannot be cleaned. Users know that this is happening when the trimmer will not run smoothly, or it cannot be started at all when no other problem is indicated. The filter is replaced by removing the back cover and discarding the old filter. Before putting it in place, work a few drops of two-cycle oil into the new filter. This will help the foam capture more airborne pollutants. Reverse the process to install the new filter. When the time comes to replace the air cleaner filter, it is imperative that the new filter be an OEM certified part that has been manufactured to the same specifications as the original.This part may be used on string trimmers, tillers, and leaf blowers by Craftsman, Ryobi, Troy-Bilt, Yard Machines, MTD, Huskee, Bolens, and Yard-Man.

A carburetor needs fuel to produce the required combustible mixture of air and gas. To get fuel, the carburetor draws the liquid directly from the fuel tank. Any excess fuel will be returned to the tank through the fuel return hose or fuel return line. In addition to providing the path, a fuel line is also responsible for preventing over-pressurization, as well as vapor lock. A fuel return line is constructed from a thick rubber material that is also fuel resistant. However, it may still become brittle and crack due to regular wear and tear. Usually, a broken fuel return hose results in symptoms such as engine misfires, loss of power, carburetor flooding, fuel leaks, and hard starting. A brand-new replacement is available here. This fuel line return is an original part from MTD. It measures 3.78 x 3.78 x 0.016 and is compatible with tillers, leaf blowers, and string trimmers made by Craftsman, Ryobi, Yard Machines, MTD, Bolens, and Yard-Man. Installation will require a screwdriver, cutters, and pliers. This fuel line return is sold individually.
