Small Engines (Lawn Mowers, etc.): Lawn mower wont start!, adjustment screws, carburetor body


Question
QUESTION: Hi John:
I have a 18" King 'O Lawn lawn mower that is at least 20 years old, but it's been working just fine till last week.  I was mowing the lawn when I noticed that one minute it was working fine, then the next it was about ready to die on me.  After a couple of minutes, it just shut off.  I haven't been able to get it started since.  I have a spark from the spark plug and I cleaned the air filter and it does have gas in it.  It just seems that it's not getting any gas.  What should I do?

ANSWER: Hello Denis:

Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. However, if the Gas is Free Flowing to the Carburetor Inlet Port, then your Problem Sounds like a Dirty Carburetor.  **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

QUESTION: I think the model no. is 3-3081-6 and the serial is 2202. Is it possible for me to just clean out the fuel line before I attempt to clean the carburator.  This way I'll know the problem is the carburator.  If so, where is the fuel line located?  Thanks for all your help.

Answer
Hello Again Denis:

I Could Not Locate a 3081 Model. I am Still Looking for a 3081 Model and will Contact the OEM on Monday for Assistance in Locating the Proper Manual. Any Information I get from the OEM, I will Forward to you in a Follow up. If I forget or Lose you Question, Please Remind me on Monday or Tuesday. However, you can do the Following. **First, Pour a Small Amount of Fuel (Approx 1oz) Into the Carburetor Throat while Holding the Throttle at Full. Still Holding the Throttle at Full, Try to Start the Engine. If the Engine Starts and Quits, then 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, Float Pin, Float 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.** The Best waay to Locate the Fuel Line at the Carburetor is to Follow the Fuel Line from the Tank to the Carburetor. Also, Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance.
