Customer Question

Second opinion] - I have a Briggs & Stratton Series 875, 190cc engine on my 2017 Self-propelled Snapper lawn mower. Recently, it started to issue white smoke, sputter, and pop. Sometimes it goes from running to run so slow it sounds as if it's going to die altogether. It sounds like an old fashioned motorcycle that sounds as if the ignition timing is way off. I haven't hit anything but I did have a tune-up done Feb. 2016. Where do I start with the test and diagnosis in order to work toward a remedy?
