Mercury 90hp 2 stroke flooding

[Dive101588]

Hi,
Have 2003 2 stroke 90hp Mercury and it floods on startup have tried , full throttle open , left for 10 mins etc just winds over no kick. Take it out of water for an hour and it starts. Seems like the choke is staying on when starting ??

Float stuck? Primer not closing?

Hi,
I put small amount of fuel in to top cylinder and cranked it started up , run from there ?

It has an electric primer valve / enricher.---Are you pushing the key in and holding it in while cranking the motor over for cold start ?

 

[Dive101588]

Yes , it is clicking each time I press

 

[racerone]

Are you holding the key in constantly while cranking it over , yes or no ?

Make sure the carbs are clear of water... etc See the brass screw on bottom side of the float bowls (hex and flat screwdriver)? Remove each, put a rag under each not to drop it. Then push clear fuel through with the primer bulb. Do this to each of the 3 carbs. If by chance the engine has sat for long periods it may have water covering the main jet. This procedure will ensure new fuel from the tank, clear the carbs, and tell you the needle in seat is working (not stuck). Then try to start it.

No

Enricher valve needs to be open while cranking.----Motors start right up with correct procedure !

Typically with my 2 stroke I have to hold the key in until kicks but doesn't start. I then turn the key without pushing and it starts with no throttle.
