Small Engines (Lawn Mowers, etc.): carburetor, briggs and stratton, internal passages

Question
Dear Mr. Bridgers,

Thank you, again, for answering my previous question.  

As you requested, my engine info is:

Briggs and Stratton
Model  12H802
Type   2349
Code   B200032758

Thanks to you, I was able to get the bowl cover off.  I then removed the "float pin" and "float" and what I think is the "needle valve".

Is the "needle valve" the small pointed rod that has one end connected to the float and the other end slides into an opening in the top part of the carburetor?  Is this part also called the "fuel inlet valve"?

Is it possible that my carburetor does not have any "adjustment screws"?  I have tried my best, but I just do not see any adjustment screws on the carburetor.

Could you tell me what "IPL" stands for in "Breakdown/IPL" and how I can get one of these.

Thank you for your help.  It is very much appreciated.

Sincerely,

Rich

Hi Rich:

The Needle Float Valve and the Fuel Inlet Valve are the Same. Over the Years the Name of the Component has Changed. The Reason for my Requesting the Model Numbers is so I can Locate a Breakdown/IPL (Illustrated Parts List) of the Correct Engine/Mower/Unit and then Direct you to the Proper Breakdown/IPL so you can See the Engine/Mower/Unit in a Breakdown Form. The Breakdown will Help you Disassemble and Assemble the Engine. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model (5 or 6 Digits) and Type Numbers (first 4 digits Only). Example: 12H802-2349. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. You May have a Model Carburetor that has NO Adjustment Screws. If so, then this Carburetors Internal Passages Must be Clean to Operate Properly.  **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. Install New Parts if Required.** 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

Respectfully

John
