Now that spring is nearly here, it’s time
to dust off your lawn mower and make sure that your yard is looking neatly
trimmed and looking good. Even though
winter has been a little mild, to say the least, that lawn mower has still been
sitting unused for a few months. What if
you were to fill it with oil, prime the engine, pull the ripcord, and…
nothing? What can you do if your lawn
mower just doesn’t start?
The first thing you will want to check on
a lawn mower that just doesn’t start is to check the fuel and the
carburetor. In fact, 80 percent of all
no-starts come from these issues. Before
you begin, you will need a few hand tools and a socket set. Also make sure to have a can of carburetor
cleaner and an air compressor.
Before anything, check the air filter to
make sure that it’s clean. If that
checks out, you will want to remove the spark plug to see if it’s wet. If it is, you will want to clean it with
carburetor cleaner and let it dry. The
carburetor cleaner serves as a solvent and removes any oil residue. You will also want to replace the fuel in the
engine if it is more than a month old, which is likely if you haven’t used it
all winter. Then reinstall the spark
plug, and give the ripcord a pull. As it
may take quite few pulls to suck gas into the carburetor, you will need to be
prepared to clean the spark plug again.
If that didn’t correct the problem, you
will then want to check your carburetor bowl for gas. There’s a possibility that your fuel filter
is plugged or the carburetor inlet needle is stuck. To check the fuel filter, you will remove the
fuel line at the carburetor. If gas does
not run out, you will want to remove the fuel line ahead of the fuel
filter. If gas then flows, you will need
to replace the fuel filter. If not, the
fuel line is plugged or kinked. Is there
any fuel in the bowl? If it’s empty, the
problem is a stuck inlet needle and seat.
Those will need to be replaced.
Please note any corrosion in the carburetor. If there’s any corrosion, the carburetor will
need to be replaced.
If you are still stumped, you will want
to clean the jet. Simply remove the
carburetor bowl nut, and then you can clean it very easily with a spray can of
carburetor cleaner. If the spray shoots
into the venture of the carburetor, it confirms the passage is open.
