Thank you everyone for all your help and suggestions regarding the broken tachometer and carb configuration.
After messing around with the carbs, I was able to drive it today; smooth idle and good high rpm. Still not as smooth as I would like but the new jets are not coming until next week so I'll keep it this way for now. I also get another instrument cluster from APE for experiment.
I got a chance to take some pictures today. The car came with bumpers detached. I then put the bumpers on this afternoon so that the car can be inspected as part of registration tomorrow.
What do you think about those Borbet Type A wheels? I'm debating whether I should put the 14" Cromodora Daytona or leave it as is. I have a new set of the Cromodora in the attics. However, these Borbet wheels are 15" and the tires on there are pretty sticky on dry surface.
I am still trying to figure out what is wrong with the original tach. If I can get that to work, the big tach will go. But then, I also like the smoothness of the modern tach. As such, I'm thinking of taking the gut of a modern Auto Meter 3.5 inch tach and then integrate that with the original instrument cluster.
