Found the idle screw which had a gold knob over it. Gave it a couple small turns to lean it out and she is running much better now. This seems to have done the trick! Thank you all for the help.

Thank you. I will dig in there today and see if I can get it straightened out. I will let you know how it goes.

Hi, thank you for a response. The quad starts right up when cold with the choke set about half way. I release the choke back to the off position after about 2-3 minutes and she idles just fine. I can leave it idling like that for quite a while with no issues.

I have not adjusted the idling screw on the carb, what would be the best way of getting at it? And do I turn in a clock-wise or counter clock-wise manner? Thank you!

Hi,

Newbie here! I recently bought my first ATV - an 01 Quadrunner 500 4x4, semi-auto, shaft driven. I love it...came with a plow/winch setup and all. Low miles, only 1250.

Problem is that after riding it for a short time (even 5-10 mins) and shifting down into neutral, the engine revs up to almost scary rpms. It doesnt die down until I shift in and out of 1st a couple times. Then when I go to shut it down, it lets off an incredible backfire. Am I doing something wrong or does this point to an issue someone is familiar with. Ive run through a tank of fuel, added stabilizer...but to no avail.

(I read through several threads and never found one similar to mine.)

Thanks!
