A BETTER CARBURETOR for the datsun z...
It all started when…
Roundtops began as a search for replacement carburerators for early Datsun Z cars. All of the originals were worn out, repair and replacement was expensive and often unsatisfactory.
I discovered that Skinners Union Carburetors was still in business in Salisbury, England as part of the Burlen Corporation. You know them as SU. SU designed the HS carb on many famous English sports cars, as was contacted by Nissan to develop a version for their new sports cars. The Datsun 1600, 2000, and 240Z were equipped with SU carbs in development. The results were impressive. As Nissan went into production, it bought a license from SU to produce the carbs in Japan to expedite supply lines. These licensed carbs are the Hitachi versions of the SU HS.
All of these eventually wore out, and became unsuitable for modern gasoline. SU never stopped making carbs for the millions of cars around the world that needed replacements and updates.
I was able to persuade SU to come up with modern versions of the venerable side draft setup. These new manufactured carbs are better in every respect to the old ‘roundtops.’ They bolt right up to the original manifolds and use the original linkage. New carbs with no core charge, delivered to your address in a matter of days.
