I've heard to be very careful cleaning out these jets. The best method is to use something softer than the brass their made of. I'm thinking a small plastic rod or something like that. Perhaps a tooth pick or sliver of one. You don't want to scratch the brass jet hole or distort it in any way. I'm rebuilding a Holly two barrel right now. I have put most everything including the jets through a chem dip paint bucket. Parts sparkle when they come out of there after a half hour or hour soak, but you do have to get most of the dirt off first or dip, scrub, dip.
(imagine a cute or dirty tagline here)
