For what it's worth here is a picture of the adjuster and springs between carbs 1 and 2, looking from the air filter side.
Number 1 on the left. The bit between the adjuster (at top) and the bottom spring is attached to No 1 spindle. Adjuster and bottom spring seat is attached to No 2 spindle. The top spring is just to hold the adjuster at the set position.
I guess if No 1 butterfly was fully closed (or some how stopped from fully closing), then screwing the adjuster down would open No 2 and also 3 and 4 at the same time. If you think that is a possibility you could try screwing the idle adjuster (on flexible cable going to bottom centre of carbs) in to partly open all the carbs and see if No 1 to 2 adjuster still moves No 2. It shouldn't.
