I have a 2004 Polaris Magnum 330 that will not start. Has spark, new carb, gets gas, cranks over, good compression, good battery, but still will not start.

Does anyone have any suggestions?

What is missing? Spark at the right time? Right amount of fuel mixed with the air? Compression over 100 psi with the throttle wide open?

So I replaced the coil and fly wheel, then the quad started immediately. But now when running, gas flows out of the over flow. I have checked the float level according to the manual, but gas is still flowing out while running. Any suggestions?

If it passes a pressure test, then either there is debris in the needle seat hole preventing the needle from seating, the float level is too high, the float is not floating properly (has fuel inside it and is too heavy) or the overflow pipe is damaged.
