    Hey all,..I just built another 50cc 2 stroke.
    This bike just has no pep..rides and hits a low speed..just wont open up..
    Im guessing its a bad carb...any advice?

    could just be that the cylinder isn't round. I've seen that more than a few times. if it gets better once it's broken in that's probably the case

    Have you checked the exhaust? If it has power without, then something could be plugged up.
    Is the throttle cable too loose? Could be partial throttle.

    if the idle screw needs to be all the way in for it to idle, that indicates a too rich condition - dropping the needle usually helps
