I have a sky hawk and the carb spits gas back into the filter and I was wondering if there is something I could do to fix it or do I have to get a new one?

It's the nature of the beast. All 2 stroke engines will produce some 'spit back' into the carburetor and the air filter. Unlike a 4 stroke with valves that isolate the intake from the exhaust, a 2 stroke will allow some crankcase pressuer, containing the fuel/oil charge to be drawn back into the carb.
There's nothing you can do to prevent it, just keep your air filter clean.

The only cure for this is to modify the engine to accept a reed block, which requires other mods as well. Best thing to do is clean the filter regularly.

CNS? I highly recommend you replace it with an NT Speed; very cheap, much simpler, more reliable, responsive, and less of a headache on a Skyhawk.
