'86 Yamaha 6hp outboard ran fine since I had it for 8 years...still starts on first pull but after it ran for 10 minutes it died and now it dies out after two seconds unless I pull out choke...then it kicks back in (2 secs) then I put choke in...it kicks in for 2 seconds...etc, etc,. It will run on fast if choke is delicately placed half way or so...but will die once I turn speed to slow.
I put in fresh gas, I checked the filter...full with gas...checked the external fuel line from the external tank...flowing fine...I even swapped with another line to be sure...I slowly adjusted the rich/lean screw made no difference at all. I figure it may be a stuck float or perhaps the Ethenol has clogged jets or something?
Is it worth it to buy a rebuilt carb kit...($33) or just clean it up/soak it in cleaner... but I would need to wrestle the old carb out....it looks pretty tough to get at....not sure I could do it.... Or should I try something else??? Would anyone have the "tear down" diagram to remove the carb?
Any advise would really be great....thanks a lot! Tom

Sounds like plugged carb jets. It just needs to be removed, disassembled, cleaned, and you'll be good to go. You can probably do it, but if not, then find someone to do it for you. Plugged carbs are not rare in outboard motors and yours should be relatively easy to do. Good luck!

Thanks Robert...I will attempt to disassemble the carb but it looks a bit tough to get at...I will go to the library to see if I can get a tear down diagram. Any suggestions on products to soak the jets in? Or is it merely surface cleaning/blowing out and then replacing?
