Re: Outboard Issue
Plus one on the dirty carb. It would also help to know how LONG it will run before it dies. Could be junk in the bowl, blocking the idle jet after starting. If it runs for a few minutes, could be the float sticking.
I would start with the carb bowl drain (if it has one). With tank disconnected, and a small white cup placed beneath, remove the drain screw. It can be a tight squeeze to get a cup under the drain, but get something there, to see if you get any grit or gunk out. If it runs clean, remove the carb, disassemble and clean.
