I think there may be a set of very early SU carbs on eBay with the round float bowl covers. Didn't these come on the 69-70 cars? It's hard to tell from the pictures but I thought I'd post a link here in case anyone is looking.

Yep! Thanks

He's got lots of 240 stuff up for sale. Seals, bushings, chrome, rocker arms. Might be something there someone needs.

water pipe on that carb/intake auction looks bent, missing the center linkage between the carbs also.

Those look like 4 screw bowls. Aren't those 70 and earlier? Or 71 & earlier?

My 71 came with 4 screw bowls, I have no idea if they were original however.

70s with Vins <7500? or so had carby w/funny float bowl cover. But easiest ID "early 70" is the lack of drain for the bowl....

Took the words right outa my mouth. That's why I'm interested in these.

Are they simialr to the Sus on a 70 roadster?

Many of the parts are shared.

So the earliest SUs were the ones WITHOUT the float drains? If so, the set I acquired for #12746 are the early ones. My car is not going to be anything special, I just wanted SUs on it instead of the hack-job injection that's on it now. Maybe I should sell my drain-less carbs and buy a different set that's less rare?

I always feel a little spooky talking about auctions I'm interested in. The carbs on 26th and 27th do not have drain plugs in the front of the float bowls. The float bowl caps are 4-screw as are the dashpots. I don't know if these are roadster type carbs. It wouldn't surprise me. There may be some other differences - vent hoses. I'm noticing the eBay carbs are missing the fuel line attachment pieces.

I'm planning to send my carbs off to Z-Therapy when the time comes. I expect to pay around a grand for each car to have them refurbish everything including the air filters. When doing something like this, it is always nice to send extra parts and pieces. That's why I'm interested.

Only having the carbs off #215 to compare to, I am trying to following some of this to make sure that I probably have the original carbs (with this car, you never know!). Attached is a pic of the left carb. It is a 4-screw, so that's good, but what are "drain plugs in the front of the float bowls"? Do I not know what we're talking about because they aren't here? And that's good (for being early), right?

Yea, mostly. The 2 liter roadster carb butterflys rotate the opposite direction. They were all four screw domes. Some had the attached plastic float and some had the loose metal float, and that was not dependent on year. Once again Nissan using up what they had on hand. The roadster SU uses a shorter metering needle with a heavier piston spring.
