I just picked up a 04 rancher from a older gentleman. Its only got 1200 miles and 240hrs. Really clean for the year, but it's running rough. I took the tank and cleaned it good and flushed it with good gas. I cleaned the carb, it was gummed up pretty bad. Also put a new plug in it. The atv will start and idle fine with the choke off but will not rev up. It spits and sputters and will die unless you back off the throttle. It will rev up somewhat with the choke pulled out some. But will still not rev all the way up. Is it worth rebuilding the carb or just buying a new oem carb? It will idle all day without the choke but will not rev up much but just a little. Any other problem that could be causing this?
