Im working on a 1999 Bayou 220 and I just installed a new carburetor today. I fired it up and its idling and running fine, but when I pump the throttle it is sticking open and I have to "pop" the throttle to get it to close and go back to idle. Any suggestions on where to start to fix the problem? Only thing I can think is the new spring in the carb is in a bind or the slide is sticking but im not sure.
Anyone familiar with utility ATV carburetor/throttle issues?

Disconnect the cables and try it manually. That will tell you whether the problem is with the new carb or the old cables. That is where I'd start.
If it's the cables, a cleaning and lube may well be all that's required.
If it's the new carb, then I'd probably try "massaging" it to either wear it in, or to illustrate where it is binding.

Try spinning the spring on top of the plunger around 90 degrees as well. With the plunger out of the carb roll the throttle and see if it sticks outside of the carb.

Thanks for the advice. I took apart the top end of the carb and cleaned it and tried the throttle and it was working fine and not sticking. After a little tuning on the pilot and throttle stop screws, I got it to quit sticking.

Glad that you got it worked out. Just be aware and careful the first few times out with it in case the gremlin rears it's ugly head again.
