My POS (work it out,the first word is 'piece'...) has been a bit of a recalcitrant starter for a while. This morning took the biscuit though. Turning over and over,then loads of white smoke when it did fire up. Tres embarrassing. The wife even phoned me as I drove off,asking if it was alright. I'm obviously going to put it in,but anyone know what causes it ? Just for my own curiosity.
