fuel leaking from intake

hi
i am no mechanical engineer but has anyone had this problem
went out today with my 2 stroke,1999 suzuki 65hp dt, ran like a bitch, took hood off and notice fuel everywhere, on further inspection we saw that it was running out of the air intake so it may be a sticky valve?
will i have caused more damage limping back, stopping every few to paddle and mop up fuel
and is the cure going to cost me whats left of my limbs that the boat hasnt already taken

Sounds like the float valve in you carburettor has stuck open. You'll just need to take the fuel bowl off the bottom and give it a clean.

i have been told to disconnect the fuel supply by the local dealer and run the engine til the fuel runs out, the float will drop alowing the suspected crap blocking the valve to clear?
will give it a go and let you all know

I'm not sure thats the best advice-you get the crap out of the valve and it's free in the floatbowl to block the mainjet. I'd take the all the bowls off and clean the whole lot out on all your carbs.

Where one piece of crap arrives to block one carb there's the potential for more...

Agree with NoS.
Stripping the float bowls isn't a big job and you'll get the chance to check what's causing the float valve to stick.
Dealer's advice would be a good course of action at sea though - may have saved you from all that paddling and wasted petrol.

if it is cr@p, also have a look where the *cr@p* could come from as well - there should be a fuel filter somwewhere (i would have thought

) if not, then now is a good time to fit one, if one is fitting then there could be somthing hanging around in the fuel lines.

took dealers advice all ok now, this is a common problem for these engines apparantly, the solution is to use a coffee filter for the fuel,boat holds 120 litres as i am new to owning my own boat i keep it fairly full, but have you tried putting 60 litres through a coffee filter, no nor have i, takes to long, told a fuel filter will help (i dont have one) but will not catch all, on the + side the engines are bullet proof!
