I'd agree with Clan here, the AAV will still be hot so should by rights still be closed and therefore addiing carb cleaner is really only going to see the carb cleaner evaporate and be pulled into the throttle body as "fuel".

When was the fuel filter last changed?

Also have you tried starting as for a flooded engine? Ignition completely off, push the accelerator to the floor and hold it there. Turn the key all the way to position 3 and hold for 7-10 seconds or until it starts, whichever is sooner. If it doesn't start on the first attempt before 7-10 seconds, release the key and allow it to come back to position 2, wait 5-10 seconds and turn to position 3 again.
When the engine fires, release the key and the accelerator to the point where it's running at a fast idle (~1500rpm) then gradually release it until it's idling smoothly.

If starting as for flooded gives a good result, you may have one or more leaky injectors, Comma injector cleaner should help with this.
