Briggs and Stratton 31P677

[KSinger66]

My Craftsman mower has this engine in it. The mower will not start or starts and runs roughly for a few minutes then dies. I have changed all filters, plug and oil. I was wondering if there is a low oil sensor and where it is located.

More likely dirt in carb causing problem.
Clean carb. This might sort it.
