Friend called with this. Unknown year 50 horse johnson, model # J50PLS0SC. They have to pump primer bulb to keep it running, buzzer went off multiple times, VRO still hooked up.

Any thoughts on why the gas isn't flowing, other ideas?

Thanks in advance!

Note that if you need to keep the engine running by using the bulb as pump, and VRO is hooked up, engine is getting NO oil.
Probably the reason for the alarm.
Until problem solved, at least add 2% oil to the fuel!
