2 stroke lingo and troubshoot

[07jkx]

Hey guys and gals! My name is Jarrod and I am just now getting into the 2 stroke world.

I work as a mechanic on 4 strokes and basic maintenance items on 2 strokes.

I just picked up a 2001 GG XC 250 (was told it was an EC... oh well). Clutch plates were stuck so I got it for a steal. Removed and soaked the plates and she runs and rides now.

1 or 2 kick bike with what I can tell is oem stuff. FMF Gnarly header with turbine core 2 silencer.

All seems good except for the infuriating searching idle, hanging idle and occasional low idle and stall when coming to a stop.

From searching this site and putting together what I could, I also think I experience "blubbering" in the 1/8 range. The bike sounds stuttery, lacking in power and then hits the pipe pretty abruptly and away I go. Kind of sketchy and unpredictable.

I am looking for any guidance on smoothing the idle and taming the hit. If there is a JD kit or something.

I do not know much about this as it stands. Any help would be greatly appreciated. Look forward to learning this new world.

Current set up:
*Carb cleaned thoroughly
*Assume factory pilot and main ( i meant to check when I had it apart - looks like main is crimped in place though???)
*I have adjusted the air screw from 1 out to 3 turns with erratic results.
*No air leaks from boots or carb (sprayed carb cleaner around it)
