i realize now the cranks must be fixed together! not the output sprocket or the clutch.

so stack the engines like you have done allready and weld a sprocket to each small bevel gear. thus a chain to connect the two added counter shaft sprockets locking it at 180 degrees.

like this a single carb will be excellent.
