If Briggs & Stratton, it will likely have two adjustment screws on the carburetor. One is for low speed, the other for full load.

Take note of how far you turn them so can return them if needed.

From your description, using the choke normally means the engine is starved for fuel so backing off the mix screw might cure it.

If not, then likely one of the jets is fouled so you will have to remove the screw(s), counting the turns as you do.

Clean the seats with carburetor cleaner (auto parts store or Walmart) and replace the screws.

They may still need adjustment after reinstalling.

I have a coleman powermate premium plus 6250 generator,put in new plug ,new filter ,changed oil,cleaned the carb,put in new gas. runs ok at half choke but when go full choke it starts backfiring and runs...

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.

I tried to start my new coleman powermate 6250/5000,

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.

Coleman 6250 generator runs rough

Fresh fuel? Does carburetor have adjustable jets? Turn the high speed jet (at bottom of float bowl) about 1/4 to1/2 CCW (looking at bottom of bowl). If no improvement, carburetor should be torn apart and cleaned. This also applies if there are no adjustable jets. Is there a fuel filter anywhere?

Coleman Powermate 6250 generator only runs with Choke on? pull

Cbronson
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.

Coleman Powermate 6250 only runs with choke closed/air restricted

A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems
