ANSWER: Hello Naraine:
You May be able to Adjust the Carburetor Mixture Screws. Send me the Model and Type or Spec Numbers Off the Engine or the Mower Model Numbers, Please. With these I can Locate the Proper Manual and Better Assist you. Does the Crankcase Oil Smell Contaminated with Gas? Thanks.

QUESTION: Dear John,
Its not the Carburetor Mixture screws, yet all i know is that I have a Honda 5.5 Horsepower Lawn Mower. No, the crankcase oil smell is not contaminated with gas.The Engine is smoking very badly. The spark plug itself is very black. I suspect the engine oil ring is broken, What is your advice? Thank You for your help

AnswerHello Again Naraine:
Black Smoke and a Black Spark Plug is an Indicator of Too Much Gas. Blue Smoke is Oil Smoke and White Smoke is a Combination of Gas and Oil Mixed. From your Description, it Sounds like the Carburetor Needs a Good Soaking and Cleaning or the Head Gasket is Blown Between the Cylinder and the Valve Galley. You can View a Breakdown/IPL of the Mower/Engine at this Site Addy, http://hayward.arinet.com/scripts/EmpartISAPI.dll?MF&app=ASP&lang=EN&TF=Mainfram and Select the Catalog American Honda. Usually a Breakdown of the Engine and Carburetor is All you Require to have as a Reference to Remove and Clean the Carburetor. If you DO Hit a Snag or Just Require More Detailed Instructions, Do Not Hesitate to Ask, Please. This should Show How the Carburetor is Attached to the Engine. Then Select the Carburetor File to See the Carburetor in Breakdown for Disassembly and Cleaning. **REMEMBER You Do Not have to Remove the Welch Plugs. The Following is the Instructions for Proper Carburetor Cleaning. 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. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.
Good Luck
