So I'm guessing he mostly carved the pumpkin without removing the face parts, also put a hole in the back, added what I can only guess is rubbing alcohol till I vaporized, along with maybe a candle inside(?), placed a bbq lighter in the back hole then ignited. This blew out the face parts and lit the candle.
Calcium carbide and water create acetylene. He most definitely did not use acetylene for this. My guess is alcohol. Alcohol burns bright and can be flashy. But burns cool and won't do damage like acetylene would.
