510 SU Datsun Carburetors

Imported into the US on imported raw engines, these are very rare.  These are mirror image like the 2L and Z, but are only 38 mm and the carbs are spaced very closely together.   Fitted to the 1600, 1800 510 cars.  These use the SSS manifold, and the Z style float chamber is indexed and tipped back to keep it level.  If fitting up a 1800 or larger engine, try some 46mm carbs.  We can build these with 2L springs and needles, with Z springs and needles on the side for experimental tuning for your application.
