When started, engine smoke BAD - as in raw oil type smoking. Engine only has @ 170 hrs on it, and is used rarely. When last used a few weeks ago, everything was fine. Now, when it starts it smoke very badly. I read somewhere to "check the crank case vent tube" - but this engine doesn't seem to have one? I'm disabled VET and have a hard time bending over to get a good look, but when I sut down, there was raw oli that sprayed out of the muffler?

Help
