I have a 2006 rancher 350 that will run at idle but as soon as it is put under a load it dies. I have been having carburetor problems with stuck floats and clogged jets. Just replaced the carburetor with a new one. So, I don't think that it is the carburetor anymore. Also cleaned out the fuel tank and put fresh gas and stabilizer in it. And tried running the 4wheeler again; still the same thing. Even took the fuel cap off to see if the fuel tank was not venting still not running under a load. Does anyone have any ideas? Thanks
