Is there a lookup posted online for Carter Service Replacement part numbers? What applications was the 4853S carb built for?
Thanks

Welcome to CHP!
As for your question, SR carbs are definitely faulty. They are full of incorrect parts and are complete JUNK. As for problems, anything inside the carb from flooding to idle problems, etc. You just don't know what will happen to them. :(

None that I know of. Sorry. :( I do not have my manual in front of me, but one internet source shows it as a Service Replacement for the 1968-70 Pontiac 350cid and 428cid cars.

Thanks. I didn't know they had issues. I have a Carter 4853S carb that I bought in the late 80s with the intentions of using it on my 1970 RAIII engine. I actually had it bolted onto the manifold but removed it prior to starting the engine for the first time because I found a NOS 800 cfm carb. At least that is what I was told by the seller.....they were a reputable Pontiac restoration and performance shop so I trusted their opinion and products. The NOS carb ran great and I used it for almost 20 years. I put the SR carb on a box in storage all this time. I pulled it out to see if it would work on my new project and it had a hand written toe tag that read '68-'70 400 and '71 455 ram air. I have no idea if the tag is correct....it is hand written so it could have come from anywhere.
I did open it up. It looks virgin inside. All the brass parts look new and I didn't see anything that looked questionable but then again I wouldn't expect to be able to easily identify QC issues at a glance. The secondary metering rods are "BE" which is the same as a 7028273 carb that I compared against. The two carbs looked identical however I did not get to open the 7028273 carb....the owner only allowed me to pull the secondary rod hangers.....
I guess I can give it a try and see how it runs. Maybe I will get lucky. Thanks for the info.
