Small Engines (Lawn Mowers, etc.): Lawn Boy model 10323, 6.5 hp 2-stroke, carburetor body, adjustment screws

Question
When idling/light load, engine cycles up and down. When I put a heavier load on it the engine smooths out. Have had carb cleaned, new plug, new fuel, etc.

Answer
Hello Tim:

You can View a Breakdown/IPL of the Mower at this Site Addy, https://lookup3.toro.com/partdex/default.cfm?xCaller=LawnBoy and Select Start Parts Viewer. Then Enter the Model Numbers and Click Search. Then Select View Assembly Drawings. Then Select the Component you Wish to View. A Leaking Intake Gasket, Leaking Head Gasket, Clogged Muffler or the Carburetor can Cause the Problem you Described. Did you Soak the Carburetor in Carburetor Cleaner? If No, then the Carburetor can Still be the Cause.  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 Accidental Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
