Small Engines (Lawn Mowers, etc.): 16 hp Kohler Command CV460, blown head gasket, adjustment screws

Question
Hello John:

My Kohler engine is shooting fuel out of the carb and flooding itself out.  It was suggested to me that the crank timing may be responsible.  Is this consistent with your experience and if so do you have advise on how to make the proper adjustments?

Thank you,
Bob

Answer
Hello Bob:

From your Description, it Sounds like the Carburetor Needle Valve is Not Seating Properly. 1st- I Suggest you  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, Float Pin, Float 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 Accidential Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model Numbers CV460S. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. 2nd- Check for a Blown Head Gasket between the Compression Chamber and the Valve Stems. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
