7.5 game fisher fuel problem

[Devonaaron]

I have a 7.5 game fisher model number 217585841. I bought it for 50 and I let it sit for a long time but I got a call from a person that needs a 5-10hp motor that was "simple" I was about to send him off when I remembered I had the game fisher so I told the guy I would get to work on it and see what I can do. I was going to sell it to the guy for 400. I rebuild outboards as a hobby but I haven't dealt with one like this. The problem is on the carb there is a inlet for 2 fuel lines, one being for the internal tank and the other being for the optional external tank. The two terminals or nubs I guess you could call them that the fuel lines hook on to are leaking. I took apart the motor as far as the tank and the air cooled cover plate as well as the carb, reed valve, and intake covers. To my surprise the piston and rings are in perfect condition and the motor is in good condition as well. So with it idling and rattling away rpms up and down. I cleaned out the carb I just dont get where or why the carb is leaking its not from the bowl to body gasket it must be the fuel inlet nubs they are mounted on the plate that screws into the carb. Im just lost there is also a orange tube I guess acting as some kind of fuel pump or diaphragm. Im sure someone has some suggestions or something to point me in the right direction. Thanks

That orange rubber thing is a diaphram fuel pump. I had a 7hp ted williams. tecumseh unit block and tecumseh carb. That little orange thing had a small slit in it. Causing a fuel leak. It wasn't obvious, and took me a while to figuire it out. Cheap part, bought it on ebay, from somebody in FL. He had a lot of parts for those motors.
Maybe that's the problem or maybe it's not, but it's one thing to check.

Best of luck.

tecumseh's are simple, if you don't want it to leak then take the time to fix it right,,,best built 2 cycle ever was.

Indeed we do! Use the search function. I think everyone is weary of the subject since it's been covered ad nauseum.
