Fuel atomization and vaporization is a big problem with todays fuel (blended for EFI) and cold air intakes.
I won’t do a cold air intake without a quality annular boosters any more.
As a general rule, that series of carbs were “universal” which means they universally fit nothing.
The idle circuit is so rich it’s crazy. Like most everything else they need T slot restricters.
They need some work but if you tune them they work well.
