"back in the day" there was 1 strip kit for AFB's and 1 for AVS's and they came with a multitude of rods/jets/needles/seats as compared to the meager offerings in the eddy kits (or at least the one (1487) for my eddy 1406 (600 elec choke)which had a few of each. My sheet lists 6 different strip kits (eddy calls them calibration kits) for the performer series carbs. carb-kit: 1403/1404-#1486. 1405-1479. 1406-1487. 1409-1488. 1407/10/12/13-1480. 1411-1489 with a total of 16 different pairs of jets available and 19 pairs of rods available which is most likely the total in all of the above kits combined ranging from a .077" to a .119" on the jets and .062"/.052" at the top of the chart to .075"/.047" (19) lower at the bottom of the list but the other day at the Rocky manginelli swap meet I bought a pair of eddy (oe AFB/AVS maybe) .120" jets so there's more to the story but you (now) know what I know
