Hi, I know this question has been asked a ton of times, but there are also tons of variations on these carbs. So I'm giving up on my Holley 1920, want to put a Carter BBS on. Car is a 1963 Valiant with a 225 and has the
"twisty" style throttle arm linkage, not the cable. Also heard this called "box" linkage or "U-shaped" throttle linkage. I found a Carter BBS that looks nicely rebuilt (fingers crossed) with the same throttle linkage and it looks like it has the same two ports I have on my Holley, small one on the left for the distributor advance can, larger one on the right for the PCV.
But his Carter also has the vacuum can on the side of carb and my Holley doesn't. I have no idea what this does, I just know the earlier carbs don't have them. Does it assist the choke somehow?
My questions are: Will this carb will work on my car? I know I need to adapt the fuel line for the Carter, but other than that I'm hoping for an easy swap.
Do I need a different Carter-style choke thermostat/housing/pushrod or does the Holley one work? I've seen Carter slant six choke assemblies available on eBay but not sure if they are actually different than the Holley one.
Attached are photos of my Holley still mounted, and the Carter I found.
p.s. it looks like there is a hole drilled in the butterfly of this Carter BBS? I want to make sure this is normal.
