Do you have trouble starting your lawnmower up in the spring? Before deciding to take your lawnmower in for repair, try these few simple suggestions. After completing them most of the time your lawnmower will fire up and run like a champ.
Pull and clean the Spark Plug
Most of the time simply cleaning the spark plug will solve your lawnmower woes. To do this, disconnect the wire attached to the end of the spark plug. Then using a wrench or a Ratchet/Socket, remove the spark plug. If the spark plug is black or wet looking, you have probably found your problem on why the lawnmower is not starting.
Using fine grit sandpaper, sand the top of the spark plug down to bare metal. Make sure you sand all around the edges of the piece of metal (tab) that sits just above the electrode. Make sure that there is a gap between the metal tab and the electrode. If you still have the lawnmower manual and a feeler gauge you can adjust the gap to the specifications. However, if there is a small gap it is probably sufficient for the spark plug to operate correctly.
Make sure the spark plug is free of dust and dry. Then screw it back into the cylinder and connect back the wire to the end of the spark plug. Then try starting the lawn mower.
