Apologies for the obscure headline Button. It's an attempt at a bit of English humour - John is a generic title a bit like Guv or Mate. Motor (spoken with an Essex or east London accent and apologies to those who are from that neck of the woods) is a euphormism for car.
Anyway, to the point: the engine has four Dellorto DRLA 45s.
