Hi Doug
I think you have two systems added together, the earlier twin SU's had
tension springs going back to the manifold to close the throttles, the later
twin SU's had rotary springs round the spindles to close the throttles,
sounds like yours has both types fitted, this may make your throttle heavier
than it needs to be.

| On the SUs on my car, there are SIX total return springs!
|
| 1: One on the gas pedal.
| 2: One on the linkage between the carbs.
| 3,4: Two on the linkages between the center linkage and the throttle
shafts.
| 5,6: Two on the throttle shafts themselves.
|
| Talk about redundancy!
| Actually the system is quite well designed, in my opinion.
| But you have to make sure that all the various linkages
| have the right clearances...
