It still sounds like a fuel delivery problem. It runs when you use the prime

Could be. I got a Sears mower with my house in 2002 and it ran fine for a
several years, but this year it will prime, but not stay running. One
problem is that there is no fuel shutoff, so you cannot run it dry when
finished. Gas in the carb probably evaporates leaving residue that gums
up the carb eventually. But no fuel shutoff also makes it hard to clean
the carb when you have a full tank of gas.

Running them dry is something I do only at the end of the season. It doesn't
seem to be a problem when used regularly.
