Hi, new here but learned a lot from reading other threads and studying parts diagrams. I'm working on a Mariner 9.9M (Japanese made I think in 1985) that sat unused for probably a decade before my uncle decided to revive it last year. He had a shop go through it then and while I am not 100% on what all was done to it, it appears (and he thinks) that the carburetor was thoroughly cleaned and rebuilt. I haven't gotten to the lower unit yet, so hopefully the impeller was replaced also. Anyway, uncle never got around to using it and I got it off of him for a good price. New fuel line and primer along with fresh gas, and off to the river. Started right up, idled good enough, and steady stream from the pee hole, so I let her warm up and took off up the river. Half a mile later I go to turn around and it dies mid-turn when the throttle is at it's lowest. After that, wouldn't start.
My steps: removed fuel filter (had particles in filter) and cleaned. Removed air intake and carb, disassembled and cleaned (looked okay to begin with). Re-assembled and connected throttle linkage and fuel line entering fuel pump.
Problem: there is a small black tube (seems like a vacuum tube?) protruding from the upper port side of the carb that I don't remember disconnecting. I can't figure out where it goes, and I cannot locate it in any of the parts diagrams for this motor available on this site. Any idea what it does and where it belongs?
