Okay guys, per this forum recommendations I finally tracked down the infamous Carter YF2100S carb everyone says works so well for my 59 Chev 3100 235 six. Had it rebuilt and attached it to the mani. (see Pic). Here's the rub, the vertical linkage the comes up and attaches to the carb bracket wont attach. When I compare the Roch "B" linkage it rests(idle) at say, 4 o'clock. The vertical linkage pushes up which opens the throttle wide open to about 2 o'clock, spring pressure pulls it back down to about 4 o'clock(idle). My Carter rests(idle) at about 6 o'clock (directly over the intake manifold, the opens to max about 4 o'clock?? The carter bottom piece (base perhaps) has numbers cast (1-788). Per google pics, most have this same base, however, the throttle bracket looks to be at a different angle allowing the rod to attach at 4 o'clock. Hope this isn't too confusing!!! NOTE: In the pic, that is the carb at full throttle, TW. At rest, it sits at 6 o'clock over the top of mani. Linkage can't work
