    It sounds like the float may be sticking

    if you feel like you can do it yourself take the carb apart and clean it real good. it has a float valve in it very similar to a toilet that stops the flow of gas when the fuel bowl is full, and allows more in as it is used up. it could have a hole in it that has allowed it to fill up with gas, and now it's not floating up, thus letting the gas flow continuously. i would suggest taking it to a repair shop/dealer though if your having to ask. its alot of small parts, screws, and things that need to be put back correctly. having all that gas everywhere would be a big time fire hazard if it ever starts and gets hot.

    Remove the bowl from the bottom of the carburetor this will probably be accomplished either by removing a screw from the bottom of it or unscrewing it from the bottom of the carb.

    Inside you will see a float with a pin holding it in place, remove this pin and remove float. Shake to see if there is any gas inside of it, if this is the case then replace it as it has failed. Attached to the float will also be a needle valve which looks like a cone on one end and is most likely hex shape on the other, this shuts off the flow of fuel into the carburetor when it is full. Inspect the cone end of the needle as well as the seat the needle fits into for wear, pitting or any dirt or forgein objects that would prevent the valve from closing properly.

    Reassemble the carb and that should do it.

    If down time is a issue I would suggest going ahead and replacing the float needle valve and seat while your into it providing the plastic float is OK.
    Also check your oil for fuel contamination and change it if present, Hate to hear you fixed the carb. just to blow it up.

    And of course you don't have to remove the shafts just to clean.

    If you decide to trty to fix it yourself, be sure to clean the needle and the chamber that it rides up inside really well. There could be (what is known as varnishing) built up on the needle and inside that chamber that is causing the needle to stick. Varnishing is when too much gas has evaoprated over time and leaves behind a residue. It will jam a carborator in a hurry.

    Let us know if you have other questions.

    look closely at the needle and seat, as sometimes varnish can be hard to see but still present enough to keep the needle valve from closing.
