Maxim takes into account the flip for guiding, but what we're talking about is a mechanical need for the gears to be loaded as per Andrew's explanation.

That looks interesting. Might look into something like that.

I'm thinking you should rig up an egg timer on the counter weight shaft. As the shaft approaches horizontal the egg timer approaches vertical and the sand changes position to shift the balance.

I'll pm you with a sketch.
Thanks for the suggestion. I might need to image longer than 3 minutes though.

This should be enough to prevent the effect you are talking about.
It's not. Definitely need that slight east bias balance.
