Sorry to bother, but I'm going to put a pair of Weber 40IDA3C carbs on the FS board & need some info because I want to give it out correctly. I figure those here are informed enough (& old enough) to know. I've tried the search function and the internet & haven't been able to find out what I want to know. The carbs are probably late 1968. One is#3121 & the other is #3153. They have (I believe) high speed enrichment tubes on the top. Can anyone confirm these are the ones only used on the S models? I also have a general idea of asking price, but any suggestions on that? I've had these so long, I can't remember some of the particulars. I can't remember for sure, but I think I had them rebuilt and remember for sure I had them jetted for a 2.7L w/ E cams & 34mm venturis. I'm attaching a picture below. Thanks a bunch!
