Question about Polaris ATV
The carb has to be rebuilt probably, but at the very least, it needs the float to be adjusted. It is pretty easy to do. If you are only going to adjust the float, get a new gasket. They may have instructions, and a little ruler, to adjust the float. If not, it should be in the rebuild kit.Take it off the engine. Empty gas into gas can. Turn upside down. Take off screws from bottom (bowl). The bulb type thingy, is the float. Where it rotates from, there should be a pin that should slide right out. Take this off, and the float should come off too. Look under where the pin was, there is a small needle valve, take it out, and by the way, set all your parts on a towel or a tray to keep from loosing them. Using a Q tip, wrapped in a paper towel (so you dont leave a little string of qtip cloth or whatever behind), wipe out where the needle valve came out of. Wipe the needle valve, and put it back in. Put the float on, and adjust it. Put gasket on, and bowl, tighten each screw so it just touches the bowl. Then tighen 2 opposite corners a little more, then the other 2 corner screws, then the first 2, then the last 2. You don't want them REAL tight, but they need a little torque on them. I think you have 2 carbs, so you can at least try one.
Spark should be okay.

Hi and welcome to FixYa,
That there is spark (even if not as strong) is significant, the ignition would then be the least likely cause of the problem.
Though the carb would be the visible indicator of the fault, it must also be considered why even the new carb is exhibiting the same problem. A common denominator then would have to be added to the equation, the fuel delivery and storage; i.e. the fuel tank, fuel cutoff valve (petcock), filter, fuel line. All must then be checked and cleaned.
Your description "...gass starts spiting out of the intake..." would lead us to primarily suspect that the float activated cutoff valve is not sealing the fuel inlet port allowing flooding.
Suggested course of action:
Good luck and thank you for asking FixYa.
