I’m undertaking one of the most exciting/complicated vehicle repairs on my 76 Lincoln Mark IV, rebuilding the carburetor. I got it all taken apart and cleaned pretty easily, but I have a few questions/issues in putting it back together. When I was taking it apart, the float and the pin that holds it were sitting in the fuel bowl. I assume this happened as I was taking it apart, but this means I’m not sure that whole assembly is supposed to work. In that same area, I made the mistake of not measuring the vacuum piston setting before I took it apart, and I thought I had to loosen the screws to get it out, which I’ve since learned was not what I should have done. How can I figure out where to set this?
I’ve put some pictures at the end of this post if they will help at all. The carb is a Motorcraft 4350.
