Small Engines (Lawn Mowers, etc.): Small Honda-clone Engine/Carburetor Situation, carburetor body, adjustment screws

Question
I have a 6.5HP Honda GX-200-clone that starts, but sucks/pumps fuel through the fuel line, into the carburetor body and saturates the air filter and begins leaking fuel at a very rapid rate.  I replaced the cracked carb float that was full of fuel on the interior, with an identical replacement that floats properly, being careful to get the needle valve seated properly, but it still leaks rapidly through the air filter? Would you have any clue as to what the problem might be?

Answer
Hello Alan:

Usually this is a Sign of a Sticking Float Needle Valve.  Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I Use Gunk). I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning. You Only have to Remove the Bowl (if Applicable), Float Pin (if Applicable), Float (if Applicable)  and Needle Valve and Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed. Then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts. Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. The Carburetor Float Needle Valve May have a Bad Seat. Some Carburetors use a Single Needle Valve with a Rubber Tip and Others use a Needle Valve and Flat O-Ring Seat. The Seat is Pushed Into the Carburetor Body where the Needle Valve Sets. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
