My generator starts fine, but shuts off after 1 minute

My 7500 watt generator has a 13 hp tecumseh engine. It starts & runs good, but shuts off after about a minute. Fuel pump seems good, inside of carb looks very clean. Good spark & compression.
Any ideas?? :confused:

Hi,
Running for such a brief period sounds like a partially clogged fuel delivery system. Could be a number of things clogged, fuel shutoff or filter, collapsed line, inlet needle's seat, etc.
Just sounds like it is burning fuel faster than it can arrive.
Peace,
Clarke
