Top replacement parts for MTD gas line trimmers

• Carburetor. The carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture then moves into the cylinder where it is compressed by the piston and ignited by the spark plug.
• Fuel filter. The fuel filter attaches to the end of the fuel line inside the gas tank. It filters particles from the gasoline as it moves from the fuel tank to the carburetor.
• Ignition module. The ignition module supplies spark voltage to the spark plug on the engine.
• Spark plug. The spark plug produces the spark that ignites the fuel in the engine.
