Mend Murray Quattro 40 Engine Carburetor Spark Plug

Briggs and Stratton powered Murray lawn mower?

After the engine, a Quattro 40, warms up it keeps cutting out every two-three minutes. I then have to re-prime and it starts again. I've changed the spark plug, cleaned out the carburettor and fuel tank, but still the problem persists. Can anyone help?

I suggest a new carb diaphragm. It incorporates a fuel pump which sounds like it has failed.
