Top replacement parts for Lehr 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.

Procedure for replacing the carburetor on your Lehr gas line trimmer

  • Wear work gloves to protect your hands and work in a well-ventilated area.
  • Disconnect the wire from the spark plug.
  • Remove the fuel cap and the drain the tank into an approved storage container.
  • Take a digital photograph of configuration of the fuel lines attached to the carburetor, or make a diagram. Pull the fuel lines off of the carburetor, using needle-nose pliers if necessary. Remove the cover from the air filter housing and then remove the air filter.
  • Use an Allen wrench to remove the 2 mounting screws that secure the carburetor to the engine. Pull the air filter housing off of the carburetor. Remove the carburetor from the side of the engine. The throttle cable is still attached to the carburetor. Take a digital photograph of how the throttle cable control cable connects to the carburetor or make a diagram. Disconnect the throttle cable and remove the existing carburetor.
  • Insert the throttle cable on the new carburetor the same way it was installed on the original carburetor. Position the gasket on the nipples of the engine mount and hold the carburetor in place. Install the filter housing and secure it with the 2 mounting screws. Using a torque wrench, tighten the screws to 25 in./lbs. of torque. If you don't have a torque wrench, tighten them reasonable tightly.
  • Referring to your digital photograph or diagram, connect the fuel lines to the new carburetor.
  • Clean the air filter if necessary before installing it. Position the filter in place and close the cover on the filter housing. Connect the spark plug wire on the spark plug.
