Engine won't start or runs rough? This carburetor assembly ensures proper fuel-air mixture for reliable operation. Moderate repair with basic tools.

This flywheel is an authentic OEM replacement part sourced directly from the manufacturer. It is part of the starter assembly on trimmers and other small engines that use a pull-start system. If the engine is misfiring, overheating, or not starting, the flywheel should be checked and replaced if necessary. Normal wear and tear can lead to the breakdown of the flywheel. The flywheel is located behind the recoil starter assembly and is attached to the engine. When the starter cord is pulled, the flywheel spins to start the engine. If the flywheel is damaged and doesn't spin fully or is seized and won't spin at all, it should be replaced. A Phillips screwdriver, spark plug wrench, Torx wrench, long-nosed pliers, and a rubber hammer are needed to complete this project. A bowl or other receptacle for storing drained fuel and work gloves are also suggested. Make sure the engine is cool, and the spark plug is removed before making this repair.This flywheel is a solid metal part that is sold individually. This flywheel is designed for tillers, cultivators, and other small engines manufactured by Craftsman and Troy-Bilt.

This is the clutch drum that houses the clutch that engages the power tools on more than 50 gasoline-powered lawn and landscape devices. The clutch sits inside this housing, which enables it to rotate. When the RPMs of the engine reach a certain point, the clutch expands and causes the drive shaft of the tool to engage. Among the different kinds of equipment that use this clutch housing are cultivators, edgers, and grass trimmers. The clutch, and therefore the clutch drum, receive a great deal of wear for several reasons: the vibration of the engine, the rapid up and down change of engine revolutions, and resistance met by the tools that are transferred back to the clutch and housing. Signs that the clutch is failing include a slow response to increased engine RPMs and an inability for the power tool to engage the drive shaft. In these cases, the clutch and housing should be replaced in order for the equipment to operate properly again. When choosing a clutch housing, it is important to select one that, like this one, is a genuine OEM certified part. This housing is compatible with Craftsman, Troy-Bilt, MTD, Bolens, Yard-Man, and Ryobi equipment.

This breather hose is a component that makes up part of the ventilation system for the crankcase with lawn and garden tools. It has a single way valve that prevents excess exhaust gases from transferring to the engine. A reed is included to help lubricate the piston as the hose moves oil to the crankcase. The tube is made with special fibers that filter and cool the air to prevent the engine from overheating.If oil is leaking from lawn and garden equipment, this can indicate that the breather hose needs to be cleaned or has been damaged. If it is dirty, it will often create blue smoke that leaves the exhaust pipe. If the smoke is dark, this is a sign that the breather hose may be damaged and need replacement.
