Hi I think i got a big proplem I have a briggs & stratton 14.5 hp Intek with ohv. Model #285777.. type 1142-e1.... it for my lawn tractor....

    I started up my machine today and there was like little white/gray  smoke coming from my muffler  when i put the blades on there was a lot of smoke coming out of the muffer I stop it to check it out and I notice oil driping from my air filter I open up the air filter and notice it was full of oil..... can anyone help  ,,I'm thinking maybe the oil ring ????    thks Mark

stupid question but is the oil level correct?

if the piston rings are worn u may have excessive blow buy which could cause oil in the air filter, u could remove the breather hose going from the valve cover to the air filter housing and run the engine and see if there smoke coming out of the breather hose if so just keep it disconected so it doesn't saturate your air filter, the oil could also be leaking past the valves into the cylinder l'm not sure if they use seals on the valves or not if they do u could replace them.

Sounds like too much oil in the crank case.  Most small engines have a crank case ventilation line that runs to the air intake side of the carburetor.  The theory is that vapour from the crank case will be sucked into the carb and burned off with the fuel.  I have a 6 h.p. Mitsubishi powered pressure washer that gave me a similar problem that you have.  The manual specified the wrong amount of oil to put in the crank case.  As it was, it was over filled.  Oil was constantly being blown into the carb intake.  Sometimes, it would make starting the engine difficult due to so much oil accumulating in the air filter.  I recommend you drain the oil and re-fill to the correct level.  Otherwise, you'll continue to have oil being blown into your carb intake until the oil level achieves the correct volume.    

Has anyone had this mower tipped on its side ?   Maybe to clean under the deck or to sharpen the blade.  This will also fill the breather and filter with oil.

Good luck,
