I am just about to assembly my Super Stearman. As the manual suggest, I plan to mount my engine (saito 120) inverted. I think the tankposition is very high for an inverted engine. If I follow the manual, will I get into trouble with engine performance like unreliable idle or lean/fat running when flying inverted?

Would you recommend me to alter the tankposition? If so, how is it best done?

Any comments from you guy´s that have flown the Stearman are very appreciated!
