Sounds like its time for a float level adjustment - BETTER YET - complete carb cleaning and setting by a qualified professional...

remove adjustment cover on rear brakes. attempt adj to loosen brakes. if seized in open position (no brakes) try removing hub from axle....if seized closed (applied) spray a lil wd 40 in brake adj hole in rear of backing plate on brakes hardware only try not to get on shoes. wipe excess from shoes as soon as possible spray w/carb cieaner wipe till no oily spots on brakes. you will find costly repairs inside either way if corrosion has gotten so bad to pit alluminum maybe replace atv b cheaper.

Have you checked the clutch safety switch(on the handlebar lever) Or the neutral switch.

ever put a clutch in? 100% sure you have the discs in right? It could very well be that it is adjusted too tight and won't release the clutch. Usually happens when you go from a bad bad over adjusted clutch to a nice new one.

if its semi automatic then youll need to rebuild the clutch which is inside the motor. if its not semi automatic, then pull the top end off where the clutch cable goes into the top end, and there will probably be a broken spring. or you just need a new clutch cable

Hey Anon, this is NOT something to "try and learn" how to do..find a professional that is will to tutor you when you do this for the first time! It COULD save you A LOT of $$$$!!!!!

If you have good spark then it's most likely a fuel issue, anything off of idle is dealing with the main jet and metering needle, clean jet and check needle for excessive wear.

Check the fuel flow through the tank valve. There are screens inside the tank that may be blocked and restricting flow.
