It should be just as it is in Biagio's picture. Can you post a picture of how it looks on your frame? Silly question, but are the cups pressed all the way into the frame?

THE LOCKNuT IS STOPPING THE CRANKS FROM BUTTING UP CORRECTLY ive followed the installation instructions and the BB is spinning beautifully the cups are in correctly there is no play in the bb if i tighten anymore the cranks become stiff to turn i havent installed loosebal flights before but ive done loads of one piece and it seems correct to me , if i ues the original drive side cone it fits perfectly but because the mongoose bb has a raised nut instead of being slotted and therfore flat those extra couple of mm are stopping the crank from butting correctly onto the spline :'(
