Took my Yamaha 9.9 4 stroke out of storage (after 2 years) and tried to
start it today.
It would not catch until I sprayed in some starting fluid, but then it
would only
rev up a bit and then die. I think it is getting sufficient fuel from a
supply tank,
but that is one thing to check. I ran the engine dry and fogged the
carburator when I put
it away last time. Could the fogging material be blocking one of the
jets? Do I have
to remove the carburator from the engine to clean it, or can this be done
with the
carburator attached to the engine? I was using fresh fuel, and this is an
almost new
engine, with about 20 hours on it. Somewhere I saw a recommendation to
partially
or fully cover the air inlet to assist in getting fuel to the engine. Is
that a good idea?

Yamaha 4-stroke 9.9 has very small carb passageways and yours may also have
the "automatic choke" on it. Almost invariably leftover fuel in the carb
will gum up inside, blocking or restriction fuel flow. Running a motor out
of gas does not get rid of everything in the carb. The owners manual
recommends the use of a fuel stabilizer to minimize the problem.

Ask any repair facility, in the spring, most repairs are carb cleanings due
to today's fuels decomposing and leaving tar-like deposits.

Chances are you will need a complete carb cleaning and a repair kit for your
motor.
