A late model Spitfire with 2500cc straight six and carburetors and a 2500 PI with fuel injection. The Spitfire suffered from a misfire at higher revs. Insufficient fuel supply saw the installation of a new Facet fuel pump. A straight forward setup and power run and it is ready for a track day. The PI was suffering from fouled plugs on 4, 5 and 6 and rich running. This was due to a worn out fuel metering unit. A replacement refurbished metering unit was installed and all throttle bodies balanced.
