Came back from walking the dog and started the generator up on the first pill. Let it warm up gradually opening the choke and then adding a space heater at the 2md level of three as a load. Then switched to the Econo mode. Ran maybe 15 minutes and died. Tried two pulls on the starter cord but it was dead. Looks like Tim may have called it right. Something may be causing it to flood. Back to the dealer tomorrow morning and I'll insist they run it for up to an hour with a load on.

If it can’t run with a space heater it’s surly not going to do a furnace or appliance. don, if they say it’s fixed, and when you go to pick it up, I’d light it up right in the parking lot like you did. If it dies out, let them know that’s unsatisfactory, call me when it’s done and don’t lie about it. Leave it right there in the parking lot, turn and walk away.....



I am thinking it may be the vent on the gas cap. Little lever you move
from "off" to "on". Should be moved to "on" while running.

It is spring loaded on the underside of the cap. It may be bad, not
allowing air to vent to tank. The fact that it ran for 15 minutes then
died and wouldn't start again makes me guess at this.

Can't imagine it suddenly getting "flooded" after 15 minutes of running
but I guess anything is possible.

Trash in the fuel? Clogged fuel filter or fuel pickup may be a possibility..
