Ok, i just rebuilt the carb new jets and all that good stuff and the reason i re-built it was because if it is idleing and you just jab the throtttle it stalls you have to feather it up a bit then your all set. This isnt good for the mud holes and what knot. but i do know quite a bit about engines and i was wondering if any one knows where there may be a low speed adjustment screw. andy help would be sweet!

I am not sure on the 250sx. But on the 200 engines there is a idle jet right under the carb. It very hard to get at to adjust. When you rebuilt it did you see a screw on the bottom?. It deffinately sounds like it is not getting fuel. How does it idel?. The adjustment underneath is just for idle. If it idles fine that is not the problem. It sounds more like the clip on the top needle needs to be moved down one notch to lift the needle some and give it more fuel at take off. Just unscrew the top of the carb. And you should see the clip underneath the spring. Remove the spring and take the needle out and move the little c-clip down one notch. I hope that helps.
