However... I doubt that this is the cause of Dizee's problems. Condensation in the bowls (carbs?) or tank (first bit of "fuel" to hit the carbs will be water) caused by warm(ish) days and cool nights, state of tune, condition of the fuel (that was left sitting), carbs, valves, cylinders etc are more likely causes.

I fully agree to your first point "over a large enough temp range", however for the purposes of the scenario posed "fuel density" is totally misleading and more of no relevance; air density on the other hand does change fuel mixture by a greater margin but we aren't in the arctic or equator, and I doubt it's the cause of the OP problem, merely pointing out the guess by the follow up post, was just that a guess.
The OP has an issue coming of the idle jet onto the main,as the idle circuit is basically fixed and working fine; for any systematic diagnostician this would suggest first making sure everything was clean and balanced on the main circuit, before looking for kryptonite in the flux capacitor ...... 
As said it's REALLY BASIC stuff, come on you keyboard experts have google and everything......
Cheers Mark.
