that feature has been around a while. Qjets had it on the lid up front in the 1970's but not a high degree of adjustability. the original BG Demon carbs had it in the air filter stud boss, you could remove the threaded stud, and use a long screwdriver and adjust it. what happened historically was this: BG Demon brand upgraded the Holley in 1990's, Holley had to spend some money to compete and introduce the HP line. then Holley sued BG in court. eventually BG went bankrupt, and Holley was right there like a vulture buying all the existing factory machinery, carbs/parts, and buildings. Holley then continued to make the Demon carbs, first finishing up what was in house in process, then changing them for the worse and cheapening them- until they were no better than a standard Holley or in some cases worse. But along the way they got all the Demon improvements. Now Edelbrock took all those Demon traits and put them in the VRS. Threaded emulsions jets, idle jets, top idle air bleeds, sight glass bowls, idle bypass adjustment, billet metering blocks, 4150/Dominator interchangeable baseplates, interchangeable boosters, etc. were all features invented by BARRY GRANT on their top line RACE carbs. these companies steal shamelessly and stomp on the ingenuity of the little guys, then take their inventions and call it their own, and re-release it. they're banking on a couple decades no one being around that remembers. Holley immediately announced all the BG features as shamelessly their new own inventions when they bought out BG, now Edelbrock is doing the same thing. reason being today's Holley, Edelbrock are not the same companies of old. They are opportunistic and owned by holding companies, faceless investors nobody ever gets to actually see.
