Hi, we have a 2007 Johnson 9.9 2 stroke
It has been running well. usually starts first pull and has never let us down, but the other day after a 15 min flat out run, when I dropped it back to idle speed it stopped and wouldn't restart straight away.
The cooling water
tell tale isn't as strong as usual, but there's no apparent blocking in the external intake grills.
The next day I tried to start it again and it wouldn't go.
I cleaned the spark plugs and retried with no luck. They were a bit black but no real gunking. The lower plug
looked a bit brown on the porcelain near the thread.
I tried pumping in more fuel
with the primer bulb and noticed fuel
leaking from the carb. See the black thing in the middle of the metal part of the pic. Not sure what that is but the fuel seemed to be coming from the small hole just above and to the right of it. Im not sure if this is normal for the fuel to come out if its flooded?
So I figured too much fuel and disconnected the fuel line and pulled the cord another 20 times and it eventually started and ran like a champ.
Reconnected the fuel line and now its running as good as ever.
So my couple of questions are...
should fuel come out that hole when theres too much fuel in the carb?
what is the little black T thing in the centre of the metal part?
how do I check the impeller or the water
flow, maybe its just a bit of sand in the telltale thats reducing flow, although I did poke a wire down to try clear it.
Is it time for a proper service
Thanks for any help and advice!
