Cheers Gup for the metering head.

problems is: ive disconnected all the pipes and fuel lines.
But the screw holding the metering head on clostest to the cooler just goes round and round.

the other bit is inside the wing so i you cant get to it.
I dont want to send my car back to the garage, all i need is the screw of and i can fit it myself.

any ideas please.
