I have a Briggs & Stratton Engine, model 123K02 engine. The engine starts fine and will run for about 1/2 hour or so but then starts to sputter, sometimes it "works" through initial sputtering but will eventually sputter again and stall out.
I have cleaned the carburetor, replaced the coil, replaced the breather, replaced the plug, replace head gasket all with no appreciable difference.
Any ideas as to what else I can look at?
Thanks,
Rick

when it starts to sputter, loosen the gas cap and see if it will continue running.
