Q:

How do you troubleshoot a Briggs and Stratton engine?

A:

To troubleshoot a Briggs and Stratton engine, you must check the main components of the engine including fuel, fire and air. Fuel allows the engine to fire. Air facilitates firing and combustion in the engine.

  1. Check the fuel component

    Begin by pulling the fuel line to the engine’s carburetor. Confirm that the fuel flows freely from the hose. If it does not flow freely, check the hose for blockage. If the fuel line has an inline fuel filter, replace it. If the gasoline gives off an unpleasant odor, flush the fuel from the gas tank, replace it and reattach the fuel hose to the carburetor.

  2. Check the fire section

    Remove the spark plug using a socket wrench of the correct size. Pull the plug wire and remove the ceramic-topped spark plug. Inspect the metallic part of the spark plug. If the J-shaped spark plug has a gasoline smell, it is old and needs replacement.

  3. Check the air component

    Clean the foam filter with hot soapy water to remove any dirt that has accumulated as a result of heavy use. Soak and squeeze the motor oil into the foam filter to help in catching fine particles that can become airborne. Wipe the carburetor with a clean rag to remove any foreign material or dirt gathered on the carburetor.
