Hi:
I am reparing an older Snapper walk-behind lawn mower with a Brigs engine. I Just cleaned the carb and it runs fine for about two minuts then it dies. After it sits for a few seconds it starts up for another two minuts. I can stop it frome dieing by choking it but when I turn the choke off it dies instantly. The mower ran fine just a fiew days before and I need to get it back to the customer.
Any help would be appreciated.
Thanks,
Nate

Sounds like fuel cap is not venting to atmosphere.

Try it slackened off.
 
I just ran it with gas cap unscrewed and it did the same thing. Since it will start just a few seconds later I'm not really sure what to check next.
