I have a Mountfield (I am UK-based) push mower with a Briggs and Stratton engine that isn't running well. The model number stamped onto the engine is: 10D902-0153-B1
It seems to stutter and is putting out more smoke lately, especially when the revs dip. The revs seem to fluctuate a lot, and dip a lot if I change the mower's direction (especially if I'm pushing it forwards and then pull it backwards).
I've attached a couple of brief videos so you can see what I mean. I would be very grateful if anyone in the know could take a look and advise.
Hello buddy ,need to have the screw in the carburetor to test run it.there is also a very small screen in the carburetor that gets clogged with debris,take apart the carburetor give it a good cleaning blow the injector with compressed air and give her a try. Good luck and GOD bless.
