Stubborn lawnmower keeps stalling

I need help with a stalling 4-stroke lawnmower engine. It will pull start, run for 30 seconds and then die.

I've ruled out everything in this AskMe here
. The problem is that the engine will only run if I sit and press the primer bulb when the engine sputters. I've had it running for about 15 minutes that way, but as soon as I stop pressing the primer bulb, the engine stalls.
So far I have:
-changed the sparkplug
-cleaned the carb
-installed new air filter
-made sure that the float is not stuck
-drained the tank and refilled with brand new gas.
It started doing this before I drained it and put it away in the fall. Any ideas welcome.
(Note to those who will tell me to get a reel mower: this lawnmower was a legacy when I bought the house and is shared with 3 other urban households. I'm keeping it running as long as I can.)
