I wonder if the inverted engine position leads to crankpin and rod end wear..then normal upright position would lead to balljoint wear. (Balljoint gets loose more because of the cap opening up than by wear IMHO).
The castor will not accumulate in the crankcase by gravity in my opinion. The high velocity crank and rod are kicking the fuel air mixture around. Hot surfaces cause the methanol and nitro to partly evaporate and leave higher castor concentration on surfaces but I do not think gravity will have a say in where castor goes in the crankcase. Sorry for theorizing on it...a heavy 6x3 prop, or low castor % in total oil % may wear the crankpin connection sooner than castor starvation, if any, due to inverted position.

Long story short David, I would leave the engine in whatever position that fits the cowling and the scale looks of your Tiger Moth..looking forward to seeing the restoration project unfold!
