I got a 2004 big bear. I just replaced the carb with an oem carb, no aftermarket. Fuel system has been cleaned and fresh gas in the tank. It cranks great and idles great. Runs perfect up to around mid to high range throttle. Then it starts cutting out and will not open all the way up. It is kinda acting like a rev limiter or firing problem. Any ideas on what this could be??? Thank you!

Did you verify if your carburetor floats are set correctly? You mite be running your carb dry at higher rpms simply because your floats are set too low and it's limiting your fuel supply.
