    any 2 strokes sm's here

    hi chaps need a bit of help with this 500, it chugs and bucks coming of the throttle

    carb is vhsb 38 dd
    jetting as follows
    185 main
    60 choke
    40 idle b50 behind that
    needle on the last clip from top
    33-1 oil mix

    am i right in thinking a bigger idle is needed?
    if i drop the needle clip one it almost sorts the bucking, hesitates a little on pull away
    and doesnt want to rev out

    any ideas

    cheers
