hello, i have just done the head gasket on my s2 and while i was at it i rebuilt the head which included a new standard ford cam, followers, lifters,valve stem oil seals. I gave a service aswell. I have just finished putting it back together and after the fuel pump not priming i renewed the relay and that sorted that problem. Now when i go to start the car it doesent start unless i get someone to push the metering flap down slightly then it runs ,but runs a little rough and seems like it running on 3 cylinders. once the cars running you can let go of the metering flap and it will run like this for maybe 2 ,3 mins then the revs will drop and it will die. So far the dizzy has been put back in the exact place it was when it was taken of, the leads are new and are in the right order, plugs are new aswell. Ive checked the timing and all of the timing marks line up. Also When it was running there was quite alot of blueish smoke, the valve stem seals are new and the turbo is ok and didnt smoke before i did the head gasket. I put in some new oil which was 5w40 this is ok isnt it. Can anybody help me please the car is driving me mad now.
cheers.
