First of all thanks so much for the rapid responses!
Well as I mentioned earlier the centerline of the tank is indeed slightly below the spray bar when the Spit is sitting on its main gear. The recommendation of disconnecting the pressure hose from the exhaust is something to think about as I didn't test that yet.
The main problem I'm struggling with is that the engine just won't seem to start shortly after it died. It's like something seems to clog up the plug which I would suspect fuel or oil residue left from the first run. When the Saito stays alive after the first start, she runs great on the ground and after take off but after a flight when the engine is stopped and the Saito is started shortly after that it just refuses to fire at all

Yep, it's an old ABC gold plated rocker cover FA120S but just broken in. I had the engine for quite some years but it's later used in this Spitfire.
It turns a Graupner 15x8... well, not in the picture but that MAS was soon replaced after this picture was taken.
I hope to install my 120ABC in my Spitfire also. It sounds like your starting problems might be a kind of vapor lock. Perhaps the heat of running and the heat buildup shortly after engine stop, since there is no cooling then, is causing the fuel to "boil" and keep it from starting. My old air cooled Corvair would not start right after shutdown because of this. Then I discovered thet there was an air flapper to be used in summer to cool the carbs. Maybe you can fit an insulator between the carb and intake manifold to keep the engine heat from being conducted to the carb. Like the gassers do. Just a random thought.
I see a couple Super Chipmunk in the background of your pics. I have the GP Giant version that I plan to put my FA180 into. I may convert it to gas/glow with a glow plug or to gas with ECDI.
Sincerely,
Richard
