I need to know what might be wrong with it. it idles fine when the choke switch is all the way up but when i put it half step down or lowest it dies.I have adjusted that small screw on the carb but it still dies after i let go of the throttle could it be something else? I could still ride it like new, jump, etc...as long as i dont let go of the throttle.
i dont have a manual for it right now so i could use a little help. Its an '05 crf150f thanks!
 
remove screw on the carb and blow air through it

then reinstall, turn 2 1/2 times from seated position then try it

the small idle circuit jet is plugging up.Take the float bowl of and unscrew the small jet clear the orifice with a wire from a wire brush and re install
