Small Engines (Lawn Mowers, etc.): Toro 6.5 throttle or rpm carb adjustment, air mixture, adjustment screws

Question
I have a 4 year old Toro personal pace with what i believe to be a tecumseh engine, 6.5 hp.  it has been running great until recently it seems as though it's not getting enough power.  to the point where today when i started it, then engaged it to start moving and mowing, it'd bog down.  do you know how I can know what screws adjust the rpm or throttle?  Any help would be much appreciated.  

Answer
Hello Tim:

If the Carburetor Has Adjustments here are the Instructions. ****The Operational/High RPM Air Mixture Screw is In the Carburetor Bowl in the Center of the Nut or Some Carburetors have Both the Idle Air and Operational Air Adjustment Screws Side by Side on the Top Side of the Carburetor. The Screw Closest to the Engine Is Usually the Operational Air Mixture Screw on this Type Carburetor.The Idle Air Mixture is the One at Top on the Side and Goes Into the Carburetor.   Some have the Idle Air Mixture Screw Going Vertically Into the Top of the Carburetor. The Engine Idle Screw is the One that Moves the Throttle Plate. The Following is the Directions for Setting these Screws. **If the Carburetor was Soaked Overnight in Carburetor Cleaning Solution and the Passages Blown Out with Compressed Air and a New Kit Installed,  then we can Set the Air Mixture Screws. Turn Both Air Mixture Screws In Until Seated. **DO NOT JAM  SNUG ONLY** Turn Both Screws Out 1 1/2 Turns. Set the Throttle to Full Open and Start the Engine. Override the Throttle by Pushing the Governor Arm by Hand and Turn the Operational/High Air Mixture Screw(bottom of the bowl) In Until the Engine is Revving Properly. Now Slow Engine to Idle. Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Now Set the Engine Idle if Required.**** I also have 2 PDF Site Addys that May Assist you Also. 1- http://www.tecumsehpower.com/CustomerService/BSI.pdf and 2- http://www.cpdonline.com/692509.pdf Here is the Site Addy to View a Breakdown/IPL of this Mower. https://lookup3.toro.com/partdex/default.cfm and Select Start Parts Viewer.
