Need help!

[Jake.]

So my go kart has been up and running well and smooth. I’ve recently installed go power sports stage 1 predator 212 kit and it has been smooth sailing ever since now. Every time I start I do full choke like usual but it doesn’t idle consistently and it eventually dies out. I haven’t changed isle speed on the screw and it has gas and oil. I have backed out the screw up where the accelerator arm is but all that adjusts is how high I can throttle. Any help is appreciated, thanks!

If the carburetor is tight, there are no air leaks and there are no mixture screws, sometimes raising the float in the carb a bit helps. I put a new carb on my Tecumseh Power Sport and had the same issues. It wouldn't idle very well if at all. Raising the float at least made it "sort of" run okay. Of course Tecumseh isn't known for their "All World" performance anyway.
