wherein there are more weights lifting than falling
That is not the flaw in this design, it is the flaw in all overbalanced designs. In a 360 degree cycle, the same amount of weight must fall, and be lifted back into place, otherwise there is no cycle. The smaller number of weights falling theoretically will have an increased leverage to make up for their lack in numbers. But for gravity to push a wheel around, PE must be lost. If it was just a matter of counting weights, then most models would spin nicely in reverse...
An additional problem now is how much energy it cost to compress the spring on the RHS of the device, which is the side that is supposed to provide the extra leverage. Are you extracting this spring energy efficiently?
What's PE? What's RHS? Do you think I need a spring board?

The counter weight falling and driving the fly wheel should be easy enough, the mechanism to keep the swing of the pendulum going is the part that needs more thought, as the timing will have to be spot on!
As for the design at the start of this thread, I do not think it will work, but that is just my opinion.

I have been wrong before!
I have been right before!
Hindsight will tell us!
The counter weight can drive the fly wheel at the axle. The axle can also turn in both directions but provide force on the wheel in one direction (you don't know you're beautiful!). The timing of the pendulum will change because of structural changes that change how a pendulum swings. But the fly wheel doesn't need to be timed, it will time itself. Know what I mean?
You could be right about the other design because it doesn't have more weights falling than lifting. But leverage turns the wheel in the drawing. Do you ignore leverage? Murilo Avalanche drives don't work because leverage is negative.
The drawing's extra leverage comes from the weight swinging outwards so in a way it is like a two stage oscillator. Can the leverage gained from the weight swinging out swing the weight back out? A factor is how long the weight will swing after it is further out and how much force needs to be applied to swing it out like that.
If a spring board is used at the shelf it could push down on a lever and get the spring board most of the way down using that leverage to have a powerful spring to swing the weight out when the weight at a nice angle to use the spring.

I'm not very smart. I don't know if my drawings are any good. Will the weight that is swinging produce leverage while it is swinging? I think the swastika is super neat. I think the mythology of it running and running is probably a gravity wheel.
preoccupied ,
In your drawing you do not show the " ledge " , so it must be separate of the wheel , standing on the ground , if you put the weight on the ledge , you loose that weight on that side of the wheel , for it is now on the ledge and not on the wheel , so it won't go down because it is further away from the axel , it will just move a little in cw , ( reversed )untill the weight on the ledge is removed , and then it will balance again . If the ledge is fixed to the wheel , it has to turn with the wheel and cannot move the weight outwards , if you use levers to move the ledge , you might as well remove the ledge and just use the levers . I think most members agree that it was weights out of balance on a wheel , but it was not the weights ( gravity )that caused the oob , JB used some other force to cause the weights to go oob .
An impulse driver is when a weight moves in such a manner whereby the device is pushed in one direction by the motions of the weight. Some believe that impulse drive will only work because of friction being different for a fast impulse versus a slow impulse. Others claim that impulse drives can work.
But forget I said anything, since being helpful is some type of sin according to cloud camper.
Sounds like your heading for your hole with the rock to pull over you!
You are helpful, and it is no sin, some may disagree with your input, but that is what makes for constructive criticism. and innovation.
You did not respond to my post regarding Murilo's hanging weight, and I was all set for you to do so. An idea regarding the concept has been born and I will attempt to describe it on a appropriate thread.
preoccupied,
The idea of an impulse drive has to do with centrifugal force pulling outward on the weight swing-out while retaining the swing on the opposite side. Milkovic has depicted this in a YouTube video, using a pendulum. Your swastika would give four hits per revolution.
The friction Jim speaks of in your case is retaining or pulling in of the swinging weights on the backside or rear of desired direction of impulse travel.
Examples of impulse drive can be found in Germany's WWII Buzz bomb, rocket engines and Kirk's billiard or pool ball topic.
As in Milosevic's example, one is always found placing the wheels for the impulse driven machine in alignment with the weight as it reaches its extremity of radius. Cf pulls at a tangent, so one should align the wheels accordingly to reap maximum pull.
