Default 400EX stalling when idle

hutchies: yes, my lid is off, and I screwed it all the way before unscrewing it.

When I opened the carb, i noticed how exactly the needle was working when I was pushing the throttle. The needle is not moving unless you push it more than 1/8, and The problem can occur betwen 0 and 1/8... My new guess would be the pilot, but i went from 38 to 42 all with same results...

Yes, there is an idle screw which is changing idle speed... do you think i should play with it?
yes, but make sure you know where it was set to so if things dont work you could set it back to stock, asuming thats how it is right now.

what i would do is get three new spark plugs. i would then go put one in and ride at 1/8 throttle or less for several minutes. check the plug color. then go do the same thing for 1/2 throttle. then do the same thing but at full throttle. i have a feeling your main is way too rich. are you running the pro meg headers? i would think you would need like a 158 main but that is just a guess compared to my curtis sparks pipe and jetting.

Too me it sounds like your needle is set too rich or the fuel/ air mixture screw is too rich. I just doubt it would be the main since the main controls 3/8 throttle and up. The first thing i would lean out the air/ fuel screw, make sure your air filter is clean too.
