Question

Answer
Hello John:

All the Carburetor Adjustments are the Same for Lawn Mower and Trimmers. There are Several Locations for the Air Mixture Screws. The Idle Air Mixture Screws are Usually Located at the Top of the Carburetor Bowl (through the Side of the Carburetor Body) and the Top of the Carburetor Body (Straight Down). If the Main Air and Idle Air Mixture Screws are Side by Side on the Side of the Carburetor (common on Trimmers and Chain Saws and ect), then the Idle Air is the Farthest from the Engine. The Main Jet Air Mixture Screw will be Located in the Bottom of the Carburetor Bowl or Beside the Idle Air Screw on the Side of the Carburetor Body. Some of the Older Model Carburetors have the Main Jet Mixture Screw Straight in from the Top of the Carburetor Body (this is Rare anymore). If you have Cleaned the Carburetor (Disassembled and Soaked Overnight in Carburetor Cleaner (I Use Gunk). Then Blow Out the Passages with Compressed Air and Install a New Kit if Required. Now Setting the Air Mixture Screws:  ****Turn the Idle Air and Main Air Mixture Screws In Until SNUG **Don Not Jam** Then Reverse Both Screws 1 1/2 Turns. Holding the Throttle Full Open, Start the Engine. Turn the Main Air Mixture Screw Clockwise Until Proper Revs are Obtained. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs. Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required. Now Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.**** Go to this Site Addy, http://www3.sears.com/ and Enter the Model Numbers in the Upper Left Search Box and Click Go. Then Visually Verify the Equipment and CLick Continue. From this Page you can View Diagrams or Parts Lists for you Equipment. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.
