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?
