Why won't my Briggs & Stratton XL4000 Portable Generator start or why does it run rough?

If your Briggs & Stratton Portable Generator won't start or runs roughly, it could be due to a couple of reasons. First, check if you're out of gasoline and fill the fuel tank if needed. Second, ensure that the oil level is sufficient. Add oil to the crankcase to the proper level or place the generator on a level surface.
