re: A second fix point?
Raj, where the strings are attached to the wheel only affect the position of the weights. The weights will be felt at their actual location and not where the strings are attached to the wheel.
A perfect example of this would be to attach an eight foot high pole with a seat on top to the bottom of a surfboard. Sit on said seat and try to stay upright. Your weight will be felt where you are and not where it is attached to the surfboard. I hope this helps.

I am going back home to Mauritius soon, and I'll have a few things to show about my SECOND FIX POINT concept once I am Home.

Looking forward to it.

A brainteaser!
Which way will the wheels in this drawing turn?
Wheel in black is a drum wheel on split axle.
Wheel in red on separate fix axle, connected to wheel in black by identical strings in green, to symmetrical points on wheels.
Weights in blue swing on levers in blue, from rim of wheel in red and swing on identical strings in yellow on rim of wheel in black.

re: A second fix point?
I would say a quarter turn clockwise and then stop.

@ Eccentrically1.
Please kindly explain why the weights would not swing an iota?
Thank you.

re: A second fix point?
Happy to oblige, my dear Eccentrically1!
Here is why I think there will be some (however small) swinging of the two weights.
1. The two wheels on separate axles, are connected by identical taut/fully stretched strings in green, at symmetrical points on their rims. Therefore any motion of one wheel in any direction will force other wheel to move in that same direction, making the weights move/swing as well.
2. The two weights swinging on the levers and strings in yellow, are applying gravitational force torque to both wheels, and because of the weights positions in the wheels, their combined net torque won't be zero. Therefore, some swinging motion is expected.
Now, I await your explanation as to why you think there will be no (however small) swinging motion of the weights.

@Eccentrically1!
I marvel at the clarity of your explanation.
Thank you.

@ ALL.
Do the explanations above make any sense ?

raj,
Yes the explanations make sense, the wheel cannot turn first because the picture is not animated, and second it is a symmetrical design.
I would think that with your experience in the pursuit you would not waste your time with such idiotic examples. If you cannot answer this for yourself, then you have blown a lot of time here for nothing!

re: A second fix point?
Hello Ralph,
I am presently in UK, with no facilities to make my presentation properly here.
It may look as if I am concentrating of petty things, with my silly brainteasers.
But I can assure you that the answers to my questions above are very important to me right now and unfortunately, I know of no other place where I can get an answer with explanations.
I KNOW THAT the weights in my drawing above will swing at least a little bit, but not in this static 2D drawings.
Until I get back home, to work on my concept testing prototype, I am trying to get second opinions from peers like you all.
Regards from UK.
