I have a 94 sport 400L that won't idle. Used to fine, but not anymore.
I noticed a rip in the intake boot (carb to engine connects to reed cage), could this seriously affect the idling?

Before the boot was torn....
I have to have the idle screw turned all the way in for it to idle, what do i need to look for in order to correct this becuase it doesn't seem like i should have to turn it in all the way.

What does the needle clip position do? I put on a different carb(stock) and noticed the needle clip was at the top notch.

Thanks for any help or ideas

 

if your intake boot is torn it will sure keep your atv from idling..as for your idle screw have you adjusted your throttle cable????

 

Im picking up a new intake boot friday, hopefully that solves some of the problems.
I have tried adjusting the throttle cable a little at a time.

Ive adjusted it at the throttle assembly as well at the carb. But i gave up once it idled. (this was with the idle screw turned all the way in to start).

 

Be sure to put the needle clip in the middel notch and to take the jets out of the carb and be sure they are all clear.

 

Thanks for the info guys...
