Re: I have a coleman powermate premium plus 6250...
If you are running the engine at full CHOKE, then it is flooding the engine, but if you meant off full choke, then the carb is still stopped up. Try soaking in carb cleaner overnight after removing jet & all rubber goods. HOPE THIS HELPS.

Do check the oil after it has tried to start. Low oil cutoff would certainly cause the problem. Look for the "lost" fuel shutoff valve... there usually is one.
Your carburetor jet is likely plugged with varnish / wax from the old fuel that was allowed to sit in the carb. You will have to remove the carb, and clean it at very least. Since you already have to disassemble it, you may as well rebuild it.
Pull the starter rope and observe the ON/OFF switch. Does it flash as the engine spins? If so, you have found the problem! The flashing light in the switch indicates the engine oil is low. Add engine oil as needed to reset the AUTO-SHUTDOWN feature and it will run again. (If everything else is healthy.)

how old was the fuel in the tank and carb bowl? This could have built up varnish and make the float heavier
Another issue that my customers bring in are 4 stroke generators that have 2 stroke fuel put in tank.
