I am working on a 1970 Eska 3 HP outboard with a Tecumseh power head, and I am trying to identify the carburator specifically so that I can buy the correct parts. I have the Tecumseh Technician's Handbook, but this carburator appears to be just a little different than those shown in the manual, so I thought I would ask. The only number I can find on the body of the carburator is 394 0016. Does that mean anything to anyone?
