Hey fellas new to the site. I bought an 03 big bear 4x4 wouldn't idle at all, but would run halfway decent once you got it moving. The carb was new from last year according to the seller. Pulled it broke it down and replaced with the rebuil kit jets and gaskets. Put everything back together and its idleing very high and if I give it gas it just kills. If I starve it for air it idle extremely high and I have to turn it off. I hope it's as simple as maybe I mixed up the jets or don't have my air to gas mix screw set correct any advice would be much apreciiated. Thanks in advance
