    I put the original nt carb 2nd gen back on.
    Now I start okay. Right now I have the idle screw all the way in. and when i start it it runs but the bike is rolling by itself, it will go for a bit then rev up, then stall out.
    I have had no issues with it beforehand.
    what the frick am i doing wrong?
    maybe tighten the cable? there is play.
    and maybe adjust the screw out is set the idle.
    can someone clarify this for me is pissing me off, lol.

    revving to a stall usually means fuel flow is blocked

    Your loosing fuel, I'm sure your using up all the fuel in the bowl then it dies

    Check your fuel line and petcock

    like that happening. not enough fuel going into the carb equals carb to run high and shut off.
    thats simple enough means i got air in the fuel line or is not giving the carb enough gas steady. means i have an air leak somewhere or air getting into the fuel line somehow.

    okay guys figured out the drama. the pic below will explain it.
    I used a powerade bottle and forgot to take out that white rubber liner. hence the carb sucks the fuel creating a vac. therefore it sucks the fuel then it sucks back in the bottle.
    much like u drink it. I take outt he rubber piece good to go. The tank is beyond fucked. is why for this.
