We have a Craftsman mower (with a Briggs and Stratton engine) that we have not taken very good care of. Not only did we not remove the gasoline before wintering it over, but we also did not maintain the air filter or spark plug. So it was not surprising that when we went to use it this spring it wouldn't start. However, with these simple steps we were able to get it running as good as new.

Total Time: 20 minutes
Supplies:
spark plug
air filter
fresh gasoline
carb cleaner
gas siphon
Steps:
Begin by siphoning out the old gasoline into a container for proper disposal. It is best to use one intended for this purpose, instead of using your mouth and a hose.
Now add fresh gasoline and put the cap back on the gas tank.
Remove the spark plug using a spark plug socket. Put the new plug in and reattach the wire.

Open the air filter housing and remove the filter. Some air filters can be washed and reused, however if it has been a long time you may want to just replace it.
Once the filter is out you need to spray carb cleaner directly into the carburetor. A few good sprays should do.
Put the new air filter in and close the housing door.
Now is a good time to try starting the mower. Be sure to prime the mower with the priming button. It may take a few tries to get the mower going.

I suggest running it for a few minutes the first time you start it. This will help get the new gas running through everything. Happy mowing!
I have a 2010 Briggs and Stratton push mower that won't start. It has new gas, the carburetor is clean, and it has a new spark plug. Could it be the fuel filter, and where is that located?
I have a Troy Built lawn mower. I have already used it this year, but when I went to use it today, it just sputtered and wouldn't start. Any suggestions?
I just tried to start my push mower and the cord is sticking, not pulling out all the way. Also gas is squirting out of the carburetor every time I try.
