85 ATC110 idle problem

[DDQ]

I am having an an usual amount of trouble with the carb on my 85 110. I just can't get it to idle consistently. I checked for air leaks in the intake but there are none. I've disassembled and cleaned the pilot and main jet. The slide and needle are moving freely. I have to give the machine some gas to get it to start. It will run fine as long as I keep my thumb on the throttle but even with the idle screw all the way in it will only idle for a few seconds then die. Any ideas what is going on?

Here is a picture of the slide position when the idle screw is all the way in.






Here is the position with the screw all the way out

Check compression. See if its low . Also ive had luck with the 25 buck ebay carbs.
