My 16hp Briggs & Stratton extended life series engines will puff some serious smoke whenever it is leaning down to the right. This is on my Quick 36. This has only happened twice and then I quickly try to level up. So I checked out the Briggs & Stratton web site for answers. In the FAQ's section, it said this will occur when opperationg engine at greater than a 15 degree angle. Well I will try to stay out of those situations but I would like to know what exactly is happening inside the engine and if it could cause permanent damage. Is the oil going to something that can't let something breathe and that cuts the engine out? After the last sentence you now know the extent of my technical knowledge. Anybody know? Thanks in advance, MV.
