This post isn't really related to daysailers, but thought I'd see if anyone might be able to help.
A 1998 Yamaha 9.9 hp outboard has come into my hands. I wouldn't be surprised if it hasn't run in a year, but the engine oil is clean, and spark plugs look ok (not great, but not fouled or rounded).
I changed the fuel, and started it. It will run if I nurse the throttle, but it won't idle (or maintain any rpm). If I leave it at a particular rpm, it will die within 10 or 15 seconds. But then it will start again easily.
Any thoughts?
