Hi All
I have an old 3HP Briggs and Stratton motor which is surging in revs at full throttle (Can see governor pulsing too).
I've removed the carb and cleaned the fuel filter mesh and replaced the diaphragm and gaskets.
This hasn't seemed to help at all. There is an mixture adjustment screw on the side, but I think that is only for idle, and it makes no difference when I move it.
Any idea what else this is likely to be?
