Andrew,

Yes, makes sense. There is a large floating counterweight on the crankshaft, but once the engine is running, centrifugal force will keep it at the end of it's range. Being a single throw crank, I am concerned if I balance the flywheel assembly and it is supposed to be weighted, I will be doing more harm than good.

Jim,
I am having everything dynamically balanced. I have machined up a mandrel to mount the flywheel on, and will first spin up the flywheel and fan, then add the pressure plate, and will have it spun up again after the clutch plates and intermediate plate is in to be sure.
