Kawasaki Bayou 220 Backfires through carb

I have a Kawasaki Bayou 220 and every time I start the Bayou it backfires through the carb.

I checked everything. I cleaned the Bayou carb, I bought a new Bayou 220 air filter. I tried new gas.

I am running out of ideas and am not sure why my Kawasaki Bayou 220 keeps backfiring through the carb.
