New to rhino and forum

Howdy from the Backwoods of south central MO. Just picked up a 2013 rhino 700 fi Camo for 600. Didn't run. Brought it home and tinkered a bit and starts and idles fine, runs a little rough once you hit the pedal. Moves when you put it in gear though. Going to be going through it and fixing things. Pretty sure gotta do oil change, head gasket, the meter has flashing E. Not really sure what all else. Time will tell.
