2007 EU3 K Series, 14K miles, no previous issues. Got a bit of an issue since the Seven came out of hibernation. Since the second time I used it this season it had been reluctant to start when cold, and when it does start the following symptoms exist until it gets warm. 1. Immediately from start there is a loud sucking sound from the air inlet (louder than I remember it anyway). 2. The engine hunts, as if it were on choke; if it had one. 3. The idle is in excess of 1500rpm; sometimes as much as 2000rpm. 4. There is a noticeable increase in fuel consumption. Once warm there are few if any of the above symptoms. The colder the weather the more acute are the symptoms, so I noticed them quite a bit the week before last. Any pointers would be greatly appreciated. Regards, Rob.
