Thumbs up Briggs Engine stops quickly

last weekend I was cutting the grass and run out of gas.
So I stopped and stored the lawn mower because I didn't have any extra gas.

Today I bought some gas, pour it in the tank and
primed the engine.
I start the engine easily but stops running quickly.
I repeated the procedure over and over but the engine runs only for about
7 to 10 seconds.

If it's running and I prime it (while running) then it doesn't shut down.

The other thing I noticed is that even when starts, I fell it doesn't have much power.

I never had any problems with the lawn mower.
I never let it run out of gas before.

Thanks in advance for any responses.

I'm no expert and I'm sure one them will chime in here soon..

Sounds like when you ran the tank dry some dirt got sucked into the carb.. There's a screen on the fuel 'pick up tube' that could be clogged. Also another screen over the check valve and/or the check valve it's self could have sucked in some dirt obstruction !?

The fact that it will run when pressing the primer bulb is a good indicator that you have a clogged carb. as it bypasses the normal path of the fuel flow through the carb.

I have the same carb. and mine needs a new diaphragm as mine has been surging lately.

Good Luck

I don't see what engine or carb you have. I would also agree that it's a carb problem, but more specifics would depend on what you have.
