My Carter go kart with a 6hp Tecumseh engine is not wanting to run without the choke off. I can run it fine with the choke on, but then when I take the choke off it dies right away, even after being plenty warm. Could it be the carb or something else?

Here are some pictures:

Next to my Talon:

need more fuel or the carb is stopped up. try opening your fuel screw a bit. your getting too much air and not enough fuel

Thanks, I'll try to adjust the fuel screw.
