Small Engines (Lawn Mowers, etc.): Valve Adjustment, valve clearance, valve adjustment

Question
I have a B&S motor. The model # is 287707 type 0224-01.  I was needing to know how to adjust the valves.  Do I adjust them with the piston at TDC or is their another position that I need to put it at.  I found the clearances online.  Intake is .003-.005 Exhaust is .005-.007.  Could you also tell me if these are the right clearances?  Thank you for your time.

Answer
Hello Davey:

I Do Not Use the Setting Called for by the OEMs. I have Found that the Following Works Best. Set the Engine to TDC. Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .008in - .010in. I have had Better Performance Out of the Mowers and Less Burnt Valves Using these Settings. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

Good Luck
