Answer
That is rather odd.  If the air is especially dry then the fuel may be evaporating or it could be leaking.  Are you in Australia or N.Z.?  Is your fuel an ethanol blend?  Ethanol blended fuel evaporates a bit quicker.  If the machine is in the sun, maybe the added heat is evaporating the fuel.  Since you have a fuel pump, there's no replacement of the fuel like a gravity feed would be.

You might try cleaning the area around the carb really good and then dusting the area with corn starch or something similar.  Then you'll be able to find an external leak.  

I'd pull the bowl off the next time I let it sit for a couple of days and see if it's empty.  

Try these and let me know what you get.  If you can't get through on here, I only answer 5 questions a day, then contact me through my website as I'm rather interested in this one and the cause.  Thanks, PK.
