I have a Skyhawk super rat 80CC with an NT carb and it ran amazing for a long time but now when i first start it i feel air pushing out of the side of the engine then it goes away should i just replace the head gasket or could it be something worse. also now it runs great for about 10 minutes then slowly dies to where it wont run at all whats the deallllll?

Is there a bunch of gas/oil residue on the side of the engine that is leaking? If so, maybe you can try tightening your cylinder heads bolts a little in a star pattern (but don't strip them) or if that doesn't work you can buy some new engine gaskets and torque down the cylinder head nuts to proper tension to help make an airtight seal.
