Patriot 105 .33 super detail conversion needle jamming

I purchased a .33 super fine conversion for my 105 Patriot airbrush and the needle dose not seem to fit the brush.  The .50 needle fits perfectly and gose through the needle barring with just a little resistance.  The .33 stops once  it hits the barring and takes force to push through and once fulley seated James up refusing to move when trigger is pulled back.  I thought it might have been bent at the factory contacted Amazon and they sent me another complete conversion kit.  That needle did the same thing my brush is only a month old and well taken care of what could be causing my problem.
