Make sure the groove in the carb slide lines up with the point on the screw. If it can't get into the groove, it won't go.

It should just screw back in, but don't over tighten it.

Help me with the groove in the carb; not a groove or flat spot in the throttle body? Again, new to nitro rc. Thanks.
You sure would think so, but it seems like something is limiting the screw from going all the way in. Does the throttle / throttle body need to be in a specific position for the idle screw to seat properly?

I just had my slide barrel out on one of my carbs,I should have took a pic!
But yes ,there should be a groove in the barrel,an yes ,it does need to be in
the right position for it to set.
The screw is a idle set screw an also keeps the barrel from coming out!

Once you tighten the screw as much as you can, does the carb body spin?

With the idle screw removed you'll be able to slide the barrel out far enough to locate the groove. Just make sure you line the groove with the opening for the idle screw and then slowly turn the screw back in. The instant you feel any resistance on the screw, turn the barrel gently to both directions and you should be able to determine if it's in the groove or against the barrel. Once you know it's in the groove you can tighten it down slowly. You're now in the position you need to be to set your idle.
You should NOT be able to pull out on the barrel at this point since the point of the idle screw will connect with the end of the groove. That's what determines exactly how far the barrel goes from fully closed and it determines the idle speed.
If it's in the right place you can look into the carb and see the barrel opening more or less depending on if you are turning the screw in or out.
