Hi, I recently obtained the car listed above it is the Landau edition. It is pretty much all original. I want to replace the carburetor but have no idea what the specs for it are. Does anyone know the original carburetor specs for this car? Thank you for your help.

Good morning.

You need to get me the number off the carburetor. There is a number on the center section in the back that goes up and down.

It will start with 170 and then a bunch of numbers.

Okay,

The specs are you have jet size of 55 on the primary and 66 on the secondary.

If you are looking for performance, change the primary to 58 and the secondary to 77. That will increase fuel flow and power.

I know this is a dumb question but are these specs what I tell the carburetor vendor in order to get the proper carburetor?

No, sorry. You need to give him the number you gave me. That is all they need.

Check this site for the carburetor.
