I have a Cub Cadet with a 17hp Briggs and Stratton mower that began blowing a whitish smoke as I was about halfway done with my lawn. It is the 6th time I have used the mower since its last oil change. When I shut the mower off, I noticed some oil drips from the exhaust. Also remembered I never change the air filter which was clogged. It is now cleaned and the dipstick reads just below full and engine still smokes. Hoping for some suggestions before I pay someone to look at it. Thanks.
