How to Repair a Lawn Mower Engine.

Step 6 Cleaning the Carburetor

As I said before the carburetor must be very clean in order to work. If a carburetor has had gasoline stand in it for more than a year it will gather a gunkey varnish which will have to be remove. This gunk can be removed easily removed by letting the metal parts sit in a jar of gasoline over night. Do not let the plastic parts stay in gasoline for to long or it can rune the plastic. Now for the individual parts starting with the float. To examine the float you will first have to remove the pin making sure you do not bend it. To check to make sure the float is working properly submerge it in water to make sure there are no holes. The float valve itself should be able to move freely and once again needs to be clean. The most common problem with a carburetor is that its jets have become clogged. They are usually made of brass and are sometimes removable. To clean them out simply run a small piece of wire trough them. The main carb body itself has many holes which can also get clogged from time to time. Use a flashlight or a laser to make sure every hole is open, and clean them out with a piece of wire.

here's a tip: when you're soaking the carb in gas, don't soak it in a disposable plastic cup. i had a bad experience with that today...

One tip when putting your carb back together: remember the float valve seat. It's small, hidden inside the carb body, and once you've removed it, you need to put the new one in. That nagging feeling you forgot something will be followed by gas on your feet and a feeling of severe embarrassment.
