Carb rebuild

[Beowulf]

How do you identify the carb used on 620? Have a 79 L20b need to rebuild carb but can not find manufacturer or numbers.

The non California 620 used a DCH 340-97 standard or -98 automatic Hitachi made carburetor. Usually Nissan, year and truck is enough for a rebuild kit as they all have a same internal parts and gaskets and the things that make them specific such as the jet sizes, isn't being changed just cleaned.

 

Not much to wear out in a carburetor. Mostly they need cleaning and perhaps a few settings adjusted.

As always, thanks.  Everything is dried out from setting so many years and butterflies are rusted from moisture.
