Small Engines (Lawn Mowers, etc.): Tecumseh engine on Yardman Snowblower, major blowout, crankcase breather

Question
I have a snowblower, started great, revved, worked perfect.  Changed the oil and spark plug, now major blowout of oil (and gas I assume) through the over fill from the carb when I rev to full throttle.  Low throttle levels do not blow out "mixture" and runs great... Any simple ideas or have I blown something internally.... Only about 6 years old and never a problem ?  Thanks and please reply to my email also....

Answer
Hello Joel:

Did you Over Fill the Crankcase? It Sounds like the Crankcase Breather is Not Operating Properly. Send me the Model and Type Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Since this is a Tecumseh Engine, I have a PDF Site Addy that May Assist you Also. http://www.tecumsehpower.com/CustomerService/BSI.pdf Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
