They look just like the originals but have a bright finish. I think I know where they are coming from. Are the major truck parts vendors selling these? has anyone seen one in use? | | | | | Joined: Sep 2009 Posts: 6,199 Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT | | Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT Joined: Sep 2009 Posts: 6,199 | As far as I now, none of our well known and established vendors are offering these overseas made wannabe Rochester B's.
For the most part, reading through many posts from fellow Stovebolter's that have purchased and attempted to use them (they carry numerous brand names, but likely are all made by the same company), most have reported that their performance and reliability is anywhere from mediocre to poor.
They look pretty, but they don't seem to step up to the plate IMHO.
Others will likely chime in further with their experiences.

(1) Applicability (2) Tunability (3) Drivability (4) Reliability (5) Initial cost (6) Overall cost (7) Parts availability
The new offshore "carburetors" compete ONLY in (5) above.

Their goal was cost reduction. It was not intended to be an upgrade. Carter responded by marketing a direct replacement carb and vowed to sell a million of them. It took a few years, but when the 1 millionth carb came off the assembly line, Carter had it gold plated and presented it to the CEO of General Motors. My father's shop was a Carter stocking dealer for many years during the 1950s. The company had a popular slogan back then- - - -"The ABCs of carburetion- - - -Always Buy Carter!" Making a "clone" of a substandard carburetor just adds another level of stupidity to that situation! Jerry

I was fortunate that my truck already had a Carter YF on it, but have two Rochester B carbs in my collection of doorstops, one from a 216 and another from a later 235.

Wonder if it’s in the General Motors Museum.😀

They had suffered 2 serious fires and we needed to find out why (we insured them). I won't bore you with all details but suffice to say the two guys "rebuilding" Rochester B and B variants just took them apart and tossed the pieces on a metal cart sitting between them which was taken to a dunk pit (uncovered...which turned out to be the cause of the fires). The carburetors had been sent in from auto parts stores as exchange carbs. The parts would soak overnight in the pit and the next day would be spent re-assembling them and labeling as "professionally rebuilt" carburetors. Occasionally a lady would come by and put them in boxes.
When I asked the supervisor where all the tags were and how they kept the parts matched, he looked at me over the lit cigarette he had dangling out of his mouth and said "Hunh? Matching parts? Tags? We can't worry about that." In a wire basket on the table where a "rebuilder" was working were a bunch of misc parts including floats, idle screws, interior pieces, etc. I asked what those were for and he said "well, we do our best but sometimes the guys work so fast to make their quota they overlook things so whatever's left just goes into those small baskets in case they need it later." He laughed and said "Wouldn't make sense to start opening up rebuilt carbs to see where you forgot the float or something. Somebody out there will return it when it doesn't work."
Hopefully rebuilders in other parts of the country did a better job. If a Rochester B, BC, etc ever made it to this place there was no way in the world it was going to remain matched and original.

You're supposed to use old coffee cans for leftover parts.
