  • i have a problem with a carb ( i think ) on a piaggio nrg. it was fine running at 65 - 70mph and now it wont go past 6000rpm, raplaced the cdi and ignition coil and lead and it still wont rev all the time, dont get why it does it with a clean carb :(

  • bigger the car the better top end the smaller the carb the better the bottom end

  • google image search

    cyclewareables mikuni needle jet types gif

    and you will see a pic of the two types.

  • Looks like you have the wrong Needle Jet(tube).

    (Jet needle is the spike)

    You have a bleed type there and you should use a primary type.

    Bleed type do not work well with 2 stroke engines due to the blowback.

    Primary types have a shield that protects against that.

    Hope that helps.

    PS: That blue book is awesome for tuning 2-strokes
