I'm just wondering if this is 'another one'. I've had three cars in the last two weeks with the cold start valve and control pressure regulator lines swapped.
Check the fuel line from the cold start valve. It should go to the 'piggy back' union on the metering head. I'm going to see a WR in the next couple of hours, so I'll photograph the lines and put the pciture up. |

Just check the part number on the pump is the right one .there are loads of pumps that will fit but different pressures and non return valves.

have the car running but its idling to low ,,would the idle valve not working the german guy mentioned cause this to happen?? adjusting the air screw has no effect or adjusting the fuel does'nt either ,,, my exhaust is blowing in 2 places would it effect the idle?

the 'air screw' bit, just allows a little to bypass the throttle valve i think. |
