>>>Have I been spoilt by my previous outboards or does this sound OK?

No it's not OK. I've had 2, 4, 8, 15 & 25hp Matiners and all have been good starters with very reliable idle.

Last week the mechanic sprayed carb cleaner, I think it was Qucksilver Power train, onto carb & gave it a 15min run on the tank. Does this mean that carb is intermittently causing problems? As it only had six days of no use. With the previous alluded to carb clean, it's either not really been cleaned or its gumming up pretty quickly, which does not seem consistent with all the replies to this thread from fellow 15hp two stroke owners.
My other dilemma is whether to continue to seek out the problem or start too make noises with the dealer having lost confidence in the engine. I guess two strokes being simple units, there must be an "ah ha there it is" moment, or are some just lemons best got rid of?

Get it back to the dealer this is not right!
I would be tempted to ask for your money back saying once engine is sorted happy to buy it back if he will give you garante it is in working condition for 3 months.

Did the dealer use your fuel tank or his?

Spraying carb cleaner is not as good as ultrasonic cleaning.

You still running fuel stabiliser in your tank? You'll notice no-one else has said they do and no-one else has said they have a problem?

Before I went to a dealer I'd want a completely fresh tank of fuel from a different filling station... ...no point blaming the dealer if you are gunking up the carb.

Oh and is it a plastic tank or metal and where are you storing it? Is it full to the brim?

Humidity right now is really high here, so risk of getting a lot of wet air in the tank airspace on a hot day then cooling down a bit and the wet condenses out leaving water in the tank. Stabiliser should help but may actually just mean there is water in the fuel to be burned off which is hard work...

The basics of cleaning a carb out seem to be removing the float chamber & thoroughly cleaning all the jets out (with an airline if possible) and reassembling to ensure that there are no leaks and the float's doing it's job!
I'm not a marine mechanic so prefer to let somebody who is fiddle about with the carbs because if they're any good it'll be done right !
It doesn't take much to block a carb up with dirty fuel/ gumming or water but running the carb dry if it'll stand for any length of time plus storing upright works (fingers crossed) for me.
