Okay, all problems have now been solved and the 7BIM runs as nicely as the single cylinder 3BIM. Getting the piston rods set at the correct position in the cylinders is crucial on these. Loctite 222 was used on the screws passing through the connecting rods to the cranks ; other wise one side will work loose and the other side will tighten up. I also used Loctite 567 thread sealant to stop the packing nuts from working loose.

I still have to put in the manifold connecting the two cylinders and then add a displacement lubricator.
