I have been having trouble with the a push Briggs and Stratton 5.5 horsepower mower sputtering and not revving to top power. I took the lawn mower apart and found a black plastic piece in the gas tank that was broken, but do not know where it goes. Any ideas?

Call a lawn mower repair shop to ask them what it might be. Whatever it is, it doesn't belong in your gas tank, that's for sure. :(
Could you post a pic of the lawn mower so I could have an idea of what model engine you have. There are a few different types of the 4.5 Briggs

My Briggs 4.5 powered lawn mower doesn't run smoothly. The engine revs and uses more fuel than it should. I think it is running too rich and that the problem stems from ethanol. Does anyone else experience this problem, and do you know what parts need repair?
