Cogged fuel filter?

Got this Craftsman model 917 6-hp lawn mower for free when I got a new

stops.

I know what you're thinking: Fuel delivery problem. I thought so too.
I pulled off the tank emptied it, blew it dry and put it back on with
fresh gas. The screen at the bottom of the tank is clear.

If I prime it more than the 5 suggested times, it says, it stays
running longer.

I did this quite a few times in order to get it hot, but it still
keeps on shutting down.

The carb is tight to the block. I tried leaving the gas cap on and off
to see if venting was an issue. Still kept doing the same thing.

The air filter was dirty, so I left it off while testing. Still won't
run.

Any suggestions?
