Summertime is finally here! The weather’s good and your lawn is growing, so it’s time to get outside and make all that green grass look its best. But after months of disuse, your lawn mower isn’t running smoothly. If it’s difficult to keep it running without stalling, there could be a problem with your lawn mower carburetor.
Before you resort to replacing the carburetor, you can try cleaning it to see if the problem resolves. Cleaning a lawn mower carburetor is a great maintenance DIY project. Here’s how to do it.
Step 1: Find the Carburetor
The location of your lawn mower’s carburetor will determine whether you need to remove it in order to clean it properly. This is something you’ll have to eyeball. You’ll most likely need to remove it, which is an easy job.
Step 2: Inspect the Carburetor
Once you’ve located the carburetor, look for what might be causing the issue. What you’re looking for here is greasy deposits or maybe even corrosion. Corrosion is possible if you left ethanol fuel in the lawn mower’s tank over the winter.
Step 3: Spray the Carburetor With Cleaner
Grab a can of carburetor cleaner — an aerosol cleaning solution that instantly dissolves gunk and corrosion. Try spraying it into the carburetor from the outside to see if that will get the job done.
Step 4: Take the Carburetor Apart to Clean It
If you’re comfortable with a bit more work and your ability to put things back together without some leaving unexpected spare parts at the end, take the carburetor apart using a screwdriver, pliers and socket wrench — exact sizes will depend on your mower. Then, spray each individual piece and wipe them all down before reassembling.
All told, cleaning your carburetor might take an hour or two, but it’s better to be thorough. A solid cleaning job will keep your lawn mower’s carburetor in the best shape possible and ensure there are no hidden problems. You likely won’t need to do it again for quite some time.
Try to make cleaning your carburetor part of your regular lawn mower maintenance schedule. Plan to do this every year when taking it out for the first time in the spring or summer. It beats having to do it unexpectedly at some point in the year when you can’t spare the time, your grass is too high or you’re just trying to get the lawn done. You can also reduce the likelihood of corrosion buildup by storing the lawn mower with an empty tank during the winter.
Carburetor cleaning is a good DIY skill to have, and once you’ve done it, you’ll probably consider it more a pride-of-ownership ritual than a chore from then on.
