i just threw this out on another topic, but ot should be repaeted fo rgeneral consumption... if you are having feed probs you may wnat to check that the holes in both the liner and the tip are on center, possible bad combinations can occure with 1/8 diffusers and 3/32 liners. the 1/8 diffuser, had a larger counterbore on the back side and throws the samller liners off center. i am sure all on this list know of this annoyuance, but it's a free bennie if you find one in the shop.
cheers
