Re: 1957 Evinrude Fastwin 18hp Carb Problems after rebuild

Browsing through 3 pages, it doesn’t look like you solved the carb issue.
I’ve had this exact issue on a couple ’50’s motors. Turned out to be the "O" ring between the upper and lower carb halves. Riser pipe I think I’ve heard some call it? I actually had one fail at the far end of a very long lake. Ended up making one from a section of fuel hose to get by.

Anyway, I know you’ve taken it apart already, but is there a chance you forgot to put it in in the first place? Maybe missing from the kit?
