Hello James:

Sorry for the Delay. High Winds Downed Trees and my Electric and Phone Service has been on and Off. More Off than On. **I Do Not Use the Setting Called for by the OEMs. I have Found that the Following Works Best. Remove the Valve Cover (on the Dead Cylinder for Twin Cylinder Engines). Set the Cylinder you are Setting the Valves on to Top Dead Center of the Compression Stroke (Both Rocker Arms will have Play in them when the Engine is at TDC) When Setting the Valve Clearance. Now Loosen the Valve Adjuster Locks and Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .007in - .009in. I have had Better Performance Out of the Mowers and Less Burnt Valves Using these Settings. Be Sure the Piston is at TDC on the Compression Stroke.**  Sorry for the Delay. High Winds Downed Trees and my Electric and Phone Service has been on and Off. More Off than On. The OEM Suggest the the Intake be Set at .003in - .005in and the Exhaust be Set at .005in - .007in . 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
