I'm wondering if you may have water sitting in the carbs, that would give off the symptoms you're saying?
Maybe worth draining the carbs just to cross it off the list.
Have a good read of this and it explains what to do, it's a quick and easy job, but use a decent fitting screwdriver so you don't mess the screws up, don't over tighten them back up, and keep some water or a hose nearby to wash any spilt fuel away.
I'd do it while the engine is cold as well.

More people are born because of alcohol than will ever die from it.
