So,you have the lean-burn carb, yes?
More likely a two-barrel BBD. That's what my '77 B200 318 had. Float adjustment is tricky and they have a tendency to leak and sink.
Valve stem seal is a definite starting point for solving oil consumption/burning issue.
The '75 El Dorado with 360 we started with came from CA and had the lean-burn carb. That thing was a total POS.
True, the lean burn carb (and system) was a failed experiment. Best bet is to chuck it and put a different non-lean-burn carb on.
BTW, some types of alcohol, such as that used in 'gasahol' and some gasline antifreeze, eats up the seals in older carb, especially the BBD. I rebuilt my BBD four times before I found out the yellow HEET I was using religiously was the cause.
Also, the seals in some older carbs tend to dry out and crack if they haven't been used in a while. (That's why I always rebuild donor carbs before using them.)
