My helper, who has evidently never used a four-cycle engine, put the gas/oil mixture in my lawnmower, which uses gas and oil separately. Understandably, the engine quit while he was mowing the lawn.
I drained out the gas/oil and filled up with gas. It will sort of start, but will not run. Engine is a 5hp Briggs & Stratton.
Does anybody have any experience with this? I suspect it may be a carburetor rebuild, but I know very little about engines.
