Hi Gordie, did research on this couple of years ago, I have a 47 Manhattan myself that ive been working on. Still working it. It has the manual choke button on the dash, and I want to go back to that.
But I found a 574S carburetor, for it, but it didn't seem to fit on the manifold to hook up the linkage. So put it on the shelf for other priority's. Now I have the time to start working it again, Have to drop the gas tank and have it cleaned out, and need to find a proper
manifold.
I actually got up tonight to ask if someone could provide me a picture of the mounting area on the manifold so I can compare to what I
have, to make sure. If it is in fact different, then I need to find the proper manifold...
