Carburetor Assembly
The carburetor's internal diaphragms are elastomers that must flex to pump fuel using crankcase pulse pressure. Ethanol in modern fuel causes these components to stiffen or 'dry out,' preventing the pump from drawing fuel from the tank into the venture. Replacing the entire assembly is the most reliable method to ensure all internal galleries and the needle-and-seat are free of varnish or debris.

Spark Plug
The NGK BPMR7A spark plug can become fouled with carbon deposits or unburned oil if the fuel-to-oil mixture is incorrect or if the trimmer is operated at low RPMs for extended periods. This carbon creates a conductive path that prevents the high-voltage pulse from jumping the electrode gap, resulting in a lack of ignition within the combustion chamber.

Fuel Pickup Body
The fuel filter or 'pickup body' resides inside the fuel tank and is made of a porous felt material designed to trap particulates. Over time, fine sediment or fuel additives can clog these pores, increasing the hydraulic resistance to a point where the carburetor's pump cannot pull sufficient fuel to maintain a stoichiometric ratio for ignition.
