Small Engines (Lawn Mowers, etc.): Lawn Mower, zama carburetors, carburetor body

Question
Hi John,
I have  Followed the Instructions you Sent as follows
;
I did Turn the Governor Shaft the Opposite Direction (Counter Clockwise) During the Governor Setting Procedure. This will Set the Governor Shaft Arm Against the Internal Governor and then the Engine should Idle and Rev Properly. 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.

Mower has the same problem. It looks like Engine stops due to load when cutting the grass.

Please advise.

Regards,

Hello Arvinder:

Can you Cause the Engine to Rev Higher by Moving the Governor Arm by Hand? The Carburetor on this Engine has No Adjustments. I Suggest you Soak and Clean the Carburetor.  The Following is a General Instruction File for Carburetor Cleaning. Even though the Carburetor Looks Clean, the Internal Passages May be Restricted with Varnish that Gas Causes to Build Up over Time. I Suggest you Make Sure the Gas is Free Flowing to the Carburetor Inlet Port. If the Gas is Free Flowing to the Inlet Port, then  **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.*** (Do Not Use High Pressure Air for the Zama Carburetors, they have Check Valves for the Primer and these are Usually Blown Out of the Carburetor if Not Careful. Allow the Zama Carburetor to Set on a Drip Pan and Dry)***. Install New Parts if Required.** If Soaking and Cleaning have No Effect, then Check the Compression. What is the Compression? How is this Mower and Engine Being Winterized and Sotred for the Off Season? 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
