Small Engines (Lawn Mowers, etc.): smoke & oil exiting through the exhaust, overhead valve engines, horizontal shaft


Question
i tilted my b&st mower to take off the blade so as to sharpen it. after reassembly, when running (it does run very well) it now is dripping oil and smoke is being developed @ the block/muffler connection. it never smoked before. do i need to replace gaskets?

Answer
Hello Carlos:

From your Description it Sounds like the Crankcase Vent was Filled with Oil when it was Tilted (tilted the wrong way). The Crankcase Vent Requires Removal and Cleaning to Remove the Oil and Allow it to Operate Correctly Again. You can View a Breakdown/IPL of the Engine at this Site Addy; http://www.briggsandstratton.com/maint_repair/manual_and_more/doclist.aspx?categ... and Enter the Model Numbers (XXXXXX) and the First 4 Type Numbers (XXXX) in the Appropriate Boxes and Click GO. Then Select Download PDF. If you cannot Locate the Breakdown, then 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. Many horizontal shaft, overhead valve engines have these numbers stamped into the OHV rocker cover. However, on certain overhead valve powered generators, the equipment manufacturer installs a decorative chrome rocker cover OVER the Briggs cover. If your engine has a decorative cover, it may be necessary to remove it in order to locate the Model, Type, and Code. You can Also Use this Site Addy; http://www.briggsandstratton.com/maint_repair/BS_modeltypecode.pdf for Assistance in Locating the Model, Type and Code Numbers of the Engine. 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
