*=closed/open measurements -- Emulsion tube F numbers can't be compared between differing carb types --
DG series carbs with series designators ending with a V (i.e. DGAV) are progressive two barrel carbs where the secondary barrel does not open until the primary barrel has opened a preset amount. DG series carbs with series designators ending with an S are synchronous two barrel carbs where both barrels open simultaneously. This convention does not always carry over to the DF series, for example the DFI is a synchronous carb as is the 40 DFAV.
