Too much fuelwill choke the engine and produce low compression. Too little fuel can do the same thing. You said that you have a new carb. You may not be getting enough fuel. Are the jets the same size as the old. Most gy6 aftermarket carbs come with a smaller size main jet. Usually around a 105 - 108. You need to see what size your old jet was. You also need to see if you have the same size emulsion tube. After markets usually have slightly smaller holes.

If your old jets are larger, I would clean them with a wire brush and use them.

Have you pulled your spark plug? What does the tip of it look like? If it is white, your running too lean. Dark brown / black, your on yhe rich side.

If you need to adjust your air mix...with your buggy on a stand/ block, adust your idle high (around 1k).. turn the screw clockwise untill the engine starts to bog down. Turn back counter clockwise untill you find your peak rpm. You may have to go back and forth a few times.
