The engine would start with difficulty but wouldn't keep running
I soaked the carb in cleaner, ringed it off and blew out the ports and installed the new parts. The diaphragm was the main culprit but a new spark plug helped too.

Air compressor engine would die under load.
During carb disassembly, noticed the diaphragm 'flap' was contorted - not making good seal.
Replacement was very simple with new diaphragm.
Engine runs great now.

Lack of power (carb) and blade cable broken
Carb diaphragm replaced easily (5 screws on side of carb)..
Jet needle then needed adjustment (trial-and-error to get most power).
Blade cable was a direct replacement of OEM part -- very easy.
Now my mower is as good as new.
