Do they even make a pilot jet smaller then 30?  Is this the reason I have to have my slide adjustment screw all the way in to idol? Everything I read says pilot jet 30-40 and nothing smaller.

If it appears to need a pilot jet smaller than # 30 there is probably something else wrong with the carb.  Needle jets and needles  get worn out and are frequently overlooked when trying to cure a rich condiiton at small throttle openings.  Bad float valves and or the oring that goes around the outside of the float valve are also a common problem.
