So I see one tank, Gas??? What about oil??? Not much for cooling it.
Looks like he extended the rear sump and that is it for oil.

It would run better if he had a little more fly wheel than a prop hub, but at least he got it running.

I don't think flyweight is that important when going through a transmission. The crankshaft, its weights and the master rod assemblies will pretty much be the flyweight.
I think his main problems are, not enough prime, he doesn't seem to open the throttle enough, its not getting enough fuel, I was going to say ignition boost too, but not sure about the high tension engines. I know the low tension engines need ignition boost for start. His method of prime is to dump gas down the carburetor. And start at idle throttle setting. He needs to be priming as it is turning, not stop and walk up and dump some gas and run away from it and then turn it over.

The fly wheel would at least keep it spinning in between cylinder firings. Crazy way to prime! Just waiting for a backfire....

Actually unloaded fly weight would not be good on the reduction assembly.
As it would violently take up backlash in coast then in power, that is if there was enough time, if not then it would act like no flyweight at all.
A dynamometer or propeller adds a load to the gear set and that load would actually oppose inertia effect from the flyweight. Running a flyweight through a gear set is not the same as a direct connection to the crankshaft. If you have ever held/seen the master/ articulated rod/ piston assemblies that are attached to the crank pin and then in a Wasp Major times that by 4 you will see there is more than sufficient flyweight in that engine.
