the idle adjustment ia on the bottom of the carb. you can just bearly reach it with 2 fingers.GPER said:I have the opposite problem, when I put my ranger into low I can't get it out of low. I have been told that my idle could be too high, I have adjusted the linkage some and it is a little better. I have gotten to adjusting the carb yet it starts and runs good so I hate to mess with the carb. Some day I'll find the idle screw and try that too.
