it is in fact a progressive carb. You run on the first barrel and when the
accelerator is moved 2/3ds the way down the second barrel is open (and boy
can you tell the difference).

Well it may just work that way. I know that on 4
barrels(my Dad has one on his Stag), that the 2
primary barrels run the car and then when you floor
it, the secondary 2 barrels open up and now all 4
barrels are pumping gas into the engine. On 2 barrles
the car may run on one barrel and then when you floor
it the other barrel open. I'm not sure, but it
wouldn't surprise me.
