We don't have much more on file for this one beyond the part number and jet size. If you're not sure whether your carb is a pre-Monobloc pattern, pull it and check before ordering, since jets aren't interchangeable across the different Amal generations.
Give the shop a call if you want help confirming which jet series your carburetor takes before you order.
