2003 Mule 3000 idles fine and runs fine once in motion, but sputters and tries to die at takeoff. It will idle fine when put in gear, but as soon as I press on the accelerator it will die if I don’t choke it. The choke doesn’t seem to be reacting as quickly as before either- it takes a few seconds at full choke for the rpms to increase. Once in motion, it runs fine again. I just rebuilt the carb, new air and fuel filters, and battery. Any suggestions?
