Another excellent informative sectional view of something from "The Cros"! 

mower .... outboards....carbs work the same... basically
some have needles some have jets some have air orifices but they all work the same... they pulll fuel from the fuel bowl via 2 circuits HS LS
That has been my instinct... that the connections are a bit loose but, of course, i don't know.There is 1 OTHER possible cause of a erratic and difficult IDLE and just above IDLE speed.
A LOOSE Ignition Cam linkage setup. Have that checked out. Some people readhust EVERYTHING with a screw that turns easily.
was thinking about that. I also thought about bringing it to a machine shop and have them cut a new tip by shaving/cutting a new cone shape back 1 millimeter so theres a sharp tip and exactly the same shape.needle packing is also important because any leakage of inbound air will serve to reduce the " pull" from the crankcase suction on the LS cct "
in the mean time since you suspect your needle is blunt, broken, whatever
you can always try your best to "sharpen it to a real pointy needle being carefull to center the new point.
nothing to loose till you find a good needle.... if that is your problem .
well you could try it ... bring them a print of what hey look like newwas thinking about that. I also thought about bringing it to a machine shop and have them cut a new tip by shaving/cutting a new cone shape back 1 millimeter so theres a sharp tip and exactly the same shape.
