I have a 439s.   Do other numbered carbs like a 514s and 592s share things like main jets, accel pumps etc?  Is the difference in venturi size?

not to put you off or anything like that, but one time a question on these came up and I found a great deal of information on the internet...do a search on the carb model and see what you find.....I did not earmark the web address....

Been trying.  Wondered if there was knowledge here on the subject.

the first site that pops up even has a download manual for the BBR

Well, if you'd be so kind, please post a link, for I am not finding the same information.  I get lots of used carbs and parts for sale in my searches.

Might be the case.   Everything on google was "where to buy".  One thing I did find discussed bore sizes that went from 1" (mine) to 1.25" and then eventually to 1.5".  Not sure how that correlates to the model number on the air horn.  Still researching. 

 

If I can't  jet the small carb to be happy with that turbo by drilling the jets (from a wide band standpoint) I'll be searching for larger bore bigger main jet units from later models and using one of those.   Either an adapter to the original intake manifold or just get a later model 23" intake.  It's quite possiblenwe end up making both a nee intake and exhaust set of manifolds, and if that's the case I'll see if I can adapt a Stomberg 97 to it.  

 

But that's way down the line.  I'm just thinking ahead in case and wondering about options...
