Review on Edelbrock 1444 METERING ROD by Jorge Toussaint

tried in Weber Mercruiser 5,7lx 4bbl instead of OEM "3step" stick for testing a little bit, it looks like performance or fuel economy hasn't changed much have, amazing, original 3 speed rods back, maybe try again if crappy E15 fuel hits us. They had more needle tips that left a bigger hole in the low vacuum - pop-up piston settings than the Mercruieser OEM square ones. The data does not exactly match the Edelbrock 1409 charts due to Weber likely having differences in the pop-up springs and primary injectors.
