hi, just getting to the last stages of finishing my project - mk 6 Escort with full S2 running gear, but have hit a problem with the running side of things, it starts up fine and runs well for about 10 seconds then starts to run lumpy and when you rev it, it seems to be choking itself with to much fuel. It kicks out quite a bit of black smoke and you can smell petrol in the fumes. Just wondered if anyone can shed some light on this, the engine is fully rebuilt and everything is the same stuff as an S2 except the fuel pump, which is an in tank uprated Fiesta turbo item for the extra pressure needed.... ? ?

Any help, much appreciated.
