Hello again,
Sorry for the wait, but I was away for a few weeks and got the new carburetor today. I guess it is a Daytona UN2, I am confused why it was sold as Zenith model 28 but what I actually got is a Daytona UN2

.
Here are some pictures.
I assume you fellows will have some comments.
Time is tight right now to get this unit installed and the truck running, but I update as things unfold.
Joerg
