Thanks Chris,
I'm back from the garage. I didn't know you could remove the throttle bodies separate from the lower box part. Apparantly you could :-)
Now, according to the manual the "inside" petrol tubes are to be removed from the "in to out couplings" (don't know proper name). I cannot do that without cutting the that permanent type of jubilee clips used.
Anyway now it's out :-)
Cheers,
