Small Engines (Lawn Mowers, etc.): Troy Built TB146EC 4 cycle tiller, thick smoke, gas flow

Question
This tiller has started and worked fine until this morning I started it and thick smoke came out of the exhaust then stalled and now the air filter is full of oil.
Checked oil which was bubbly and creamy in color, replaced and tried to restart.( It doesn't seem to feel smooth while pull starting, feels like something loose in motor???

Your breather may be clogged up or not installed correctly. Another reason is when you carburetor starts to flood do to gas flow is to much for the engine it will leak down into the engine and cause a smokey problem. Drain the oil and rebuild the carburetor see if that helps
