Another tiny update!
Having got all the spark plugs in place I suddenly thought "Hang on its going to be a bit tight in there!"
So I decided to drop the engine and oil tank in and dry fit the internals to the fuselage, low and behold there is a rogue spark plug.

Now I had to go over all the reference materials I had, to find not only images of C.IIa in the earlier configurations but also the left side! Trust me there are few and far between that have been published. In the end I found one image that showed how the spark plug was attached, which makes sense really but I want to be accurate - basically while the others are on the vertical the front is on the horizontal.
so with all the plugs attached there wasn't really anything I could do until my Taurus order arrived.
PING PONG
(what can I say its an Asian door bell!) 

So with my order in hand, Thank you Lukas! i went to work removing the parts needed - I managed to get the intake manifold parts in place and on the kit, it was a chore and really should have done it before painting/building but hey.... .more photos to follow!
