Hi Roger,
Some good points:
1. The cable outer needs to be free to move in the adjuster. This is also true of adjusting the balance via any method.
2. Before starting the adjustment procedure I slackened the lock nut (there is now only one because the other is now permanently attached to the bracket), wound it completely off the adjuster so that it just 'hangs' on the cable. At the end of the process when the carbs are in sync, wind the lock nut back into place and tighten it as normal.
3. After I have removed all of the bracketry I used some lock wire to secure the cable outer to the adjuster (just as I used to do).
4. The only additional weight on the carb socket during normal operation is the weight of a small plastic Lego gear. Granted, there is additional weight during balancing but it is in place for less than 10 minutes.
5. In my installation there is no interference between the servo mechanism and the throttle or choke cables. In the Eurostar the choke cables are at 90 degrees to the throttle cables.
6. The project was a suggested starting point for others. I dare say that there will be modifications needed to take into account other installations. It does require some affinity for mechanical tinkering.
7. Whilst the torque of the servos that I used is quite impressive, the interference fit of the Lego gear on the adjuster is less so. It is therefore important to make sure that the friction of the system is not too high for the adjustment mechanism components.
In the past I have normally been the one stood at the business end whilst a fellow pilot operated the throttle. I found it a wholly unsatisfactory method of adjusting the balance; the noise, danger and wind make for a very unpleasant environment.
