Small Engines (Lawn Mowers, etc.): leaking oil, crankcase oil, crankcase breather

Question
Your question was

"Good morning Mr. Dunn,
I have a craftsman 700 lawn mower 190cc, key start or pulley purchased in summer
of 2009. I keep my lawn mower in the dining room to keep it from the elements.
Before using it on March 19, 2010, I checked the oil, and it was dry. I put in a
quart of oil, and it smoked so bad, the neighbors came outside. After parking it
for 24 hours, all of the oil had leaked out! Help. thank you, from Memphis, TN"

Answer
Hello Elizabeth:

>>Sorry for the Delay. I have been Unable to Answer Questions Due to Health Issues. Thanks for Understanding.
>>From your Description it Sounds like the Crankcase Breather/Vent is Restricted and the Lower Crankcase Oil Seal is Bad and Requires Replacing.
>>Send me the Model and Type or Spec Numbers Off the Engine and the Unit/Mower Model Numbers, Please. With these I can Locate the Proper Manual and Better Assist you. The Engine Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. The Unit/Mower Model Numbers are Usually Located Under the Seat on a Sticker on the Body of the Mower.
>>If you Hit a Snag or this Does Not Correct the Problem,  I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck

Respectfully

John
