Dave Otto, Dave (steamer), Graham, Roger, thank you for you kind comments, it really means a lot coming from such accomplished builders.
the Carb needed to be rebuilt because I was not happy about a couple of things.
The adjusting screw was "knurled" by slipping the screw into a piece of 3/32 brass tube and lining up the edge of a file and rolling the file along the head pressing down to form the ridges.
A pencil to give it some scale.
I also added a proper flange to mount the carb to the manifold, it still needs a little shaping and the throttle lever added.
