Yeah i got a strong spark to each plug and the buzz of the fuel pump is there but when you turn the key it fires once then nothing just the starter trying its hardest. 
As for the flap moving freely it feels kinda spring loaded at the moment and only moves about 1cm
It is spring loaded but should move about 5cm's
If you take the induction pipe off the top and grab hold of the bolt on the flap you should be able to move it without too much trouble to about 5cm's up I think
Anyway just realised who you are, the new one i'm sending you should sort this out! or give you some spares at least!
