Thank you. I didn't spend nearly enough time cleaning them on my rebuild. Didn't realize all that was in those clusters.the small tube that sticks up vertically from the primary cluster is the high speed bleed. the small hole on top of the primary cluster is an idle air bleed along with another idle air bleed on the side of the cluster. the large brass tube coming out the bottom of clusters (primary and secondary) are the emulsion tubes. the small thin brass tube sticking out of the bottom of the primary cluster is the idle jet.
