R16 HJB38W carb query

[CSP311]

My car/engine didn't come with manifold and carbs, and I purchased a manifold with 1 carb ages ago. The carb was off the manifold (it was all cheap).

The carb I have has 90 degree nozzles, has HJB38W F3 on the fuel bowl id plate, the fuel bowl connector is 90 degrees to the bowl (going to the nozzle), not angled down.

A search here says the 3 indicates roadster. Does the F indicate front carb, or how do I work out which I have, or is there no difference? As I require another carb to make a pair. The picture on the carpartsmanual site shows the carb I have, but unsure on the list of part number what is what.

Thanks in advance.

The rear carb has a vacuum port on the bottom of the carb for distributer vacuum. Front carb does not.

Joe is correct that the rear carburetor has the brass barb for the vacuum line. If you need another carburetor or parts let me know. I am finishing up an early and late set of R16 carburetors now and will have them available for purchase on my site after the Solvang show this week. Check out the site at sincitydatsuns.com
