You need to buy a copy of the Bentley Official Manual for '70 thru '79. Complete carb breakdown and explanations.
The "butterfly" is the choke (or strangler). After the engine is warmed up, the choke opens (vertical).
There is a "spring" coiled up inside the ceramic cover on the right side. It's actually a bimetal.
If you have to cover the carb even after warmup, more than likely there is a vacuum leak somewhere.
