My tin of Carb cleaner is an aerosol, the fluid is expressed under gas pressure. I'd try that. Failure to idle? it probably is the idle jet. Same cure.

Hope I can get a tin of that in Greece - can't take it on the plane.

I suppose that's the problem with flying Squeezyjet or Ryandross. If it were me and I hold baggage, I'd try to smuggle a tin inside a plastic bag wrapped in some old tee shirts.

Well actually I am flying Aegian, and they all follow the same regs. So yes I could smuggle it, but the question is: should I? perhaps...... or not.......

Carb cleaning aerosols are used extensively by the motor cycle fraternity. Any bike shop will stock it.

Guilty as charged, I bought it for my old bikes, but it works well on my old SU carb on the minor and I've used it on my cheap and nasty 850w genny, Honda mower and Riobi strimmer. It's even been used on a 10cc petrol engine for a model aircraft.
It might be somewhere to buy it in Greece. It's help if you spoke the language tho'. I once had a terrific time trying to buy brake pads from a French Ford Dealership where no english was spoken and I didn't know the technical term ("bloquettes").

Anybody got a link to a service manual for a Yamaha F2.5?
I have found the owner's manual on the web but nothing which shows me where the carb is or how to dismantle it.

No, but if you're at all handy with machinery, I suggest a step by step approach, assisted by a smart phone or digital camera. As you progress with dismantling, take a photograph at every stage. Pay particular attention to the position of the needle. When the carb's in pieces, use the cleaner and re-assemble in the reverse order of the photographs. It worked for me with my ****ty Chinese generator. It's still working, anyway.
BTW I don't recommend the Allard Coles "Maintenance and repair for Outboard Motors" book in general as there's a lot of really basic stuff before you get to any meat in the text and even then there are no "work rounds" in the book nor does it warn of ant pitfalls. But you might find the section on cleaning and setting up the carb useful if you can't find a repair manual.
One last thing. I went back to your original post. It certainly sounds like the the mixture is too lean. This may well be gummed up jets, but if you have cleaned the carb and the problem persists, you might have to raise the needle in the carb a notch. Clean it and try if first though, it's more likely to be gunge in the carb if it's run well in the past.

Keep it simple! Just drain ALL the old fuel and replinish with new mix...If it runs ok,well Happy Days..
Dis-assembly/ cleaning should be avoided if possible, as it can very often compound the origional problem..
Modern petrol does not winter very well and should always be drained..This simple proceedure solves many
starting and running problems..
Disposal-Well i just dump it in the diesel tank of the boat as i dont have a petrol car,some say a small quantity
helps prevent diesel bug.(heresay and not convinced!!)
