The Saito should run great inverted, when the engine is inverted the carb can be moved to the up position. If the tank is higher then the carb you can use a Cline fuel system (fuel regulator) Here is their web site http://www.billsroom.com/pcfs/ They can explain how is works better then I.
I thinks its Byron who also sells a fuel regulator. I'm using the Cline on a GP Super Stearman with a Saito 180 and it works fine.
Did you get a chance to go to that thread I mentioned in my previouse post? They call it the Saito Club. There is a lot of good info on Saito's
