Thanks AV and MF, it will be a little bit of work to pull it apart to get at the carbie so I may not get back to you for a few days, (probably be out shopping for a new Husqvarna).
Is there a way I can diagnose the air leak?
The saw seems a bit like myself perfectly ready to go to work until I get there. I always said I didn't mind going to work it was just the eight hours they expected me to hang around before I went home.
