Starting my S40 2.0T
 

I have an auto S40 2.0T which seems to take forever to start.It kicks over with a small puff of black smoke & the stench of fuel in the air.After it starts it runs fine.When the car is parked for a short period of time,eg. filling up with fuel,it has no trouble starting.I use premium unleaded & the car has 50 000kms.Can any one help (gamster@tpg.com.au)
