Reviving an old quad

First post and also first 4 wheeler! Picked up a 2000 sportsman 500 yesterday. It belonged to a good friend of mine but it had been sitting for a few years. Cleaned the gas tank out, replaced any bad fuel lines, took the carb out and gave it a thorough cleaning. I got it to start a a couple times and it will idle but not good. When I give it any gas it wants to die. Its getting gas to the carb. Is there anything else I need to check? Also to note, the air filter has a big hole in it, I just haven’t had the chance to go grab a new one. Could that affect anything?
