The best way to get your lawn mower carburetor cleaned for sure would be to take it to a lawnmower or chain shop. They will have specialists there who will be able to clean it for you, tune it up and getting it running nice and smoothly for you in no time.

However, if you wish to undertake the cleaning yourself, then it can be done in a few steps. The equipment you will need is a good handful of rags, carburetor cleaner which can be purchased for any home store, compressed air, newspapers and a metal wire.

The first thing you need to do is to get your lawn mower on a flat surface and make sure it is not connected to the power. If you look closely below the carburetor, then you should be able to locate a nut which will come off if you unscrew it. This is where the newspapers come in handy as removing the nut may cause some oil to leak out.

Using the carburetor cleaner, spray the bottom cup of the carburetor and the plastic float valve and wipe away any muck, filth or debris using the rags. Doing this will help the engine to fire up more quickly and easily.

Spray the cleaner into every remaining part of the carburetor and wipe it clean, making sure than you remove all signs of dirt. Make sure you check that every hole is clean, use the wire if you come across hard to reach places. Some people find that using compressed air gets this job done a bit better.

Reassemble the carburetor, making sure that everything you removed is back in the right place and that it is all screwed on tight to avoid anything coming loose. Turn the fuel line back on, prime the engine and give a good hard tug on the pull start and your lawnmower should power right up!

Cleaning the Carburetor is quite easy, once the carburetor is removed.

All you need is common sense, and a basic toolset, with rachets etc. The fuel bowl of the carburetor is easy to remove, by removing the screw which is at the bottom of the bowl. Make sure there is no fuel, else disconnect the connection between gas tank and carburetor.
You have to remove a few parts ( engine cover, fly wheel etc) to be able to get access to the screw to detach the carburetor.

They have purposely made this task appear difficult, by making opening of the carburetor not easy. First time it took me a few hours to figure this out. Today, it only took me 10 mins to open everything.

You might want to check your fuel lines, as they do clog once in a while. That's what happened to my mower to but I put in a new fuel line and it fired right up.
