...That sounds a lot like the scenario I described in my first post in this topic.
It's easy enough to disable the temperature compensators,the anti run-on feature and the throttle bypass valve on ZS carbs if you have difficulty adjusting them. Once you do that, they are pretty much equivalent to the SU's in terms of complexity.
Of course you do have to maintain an intact air valve diaphragm on a ZS carb, but they usually have a pretty long life span.
