Well no, it would be pretty unlikely for that to happen. If the gas freezes, it is only because it has water in it, and the engine probably wouldn't even run if it had frozen water in the carb.

What happens is that people rev the engine up and put a load on it before it has a chance to warm up. The piston grows quickly from the heat of the load, but the cylinder is still cold and contracted. This can cause cold seizures.
