This is an Amal Monobloc carburetor, part number 389/51, built in the 1 3/16 inch (30mm) size with the chop-bowl float chamber body. It comes jetted from the factory with a 310 main jet, 106 needle, #3 slide, and #30 pilot jet - a specific jetting combination, so if you're setting this up on something other than what it was originally spec'd for, plan on rechecking the mixture across the range.

The catalog notes this carb is meant to run paired with a 389/19, and that combination calls for 376/140 and 376/141 to complete the installation. If you're ordering this one, make sure you've got those other three pieces sorted too, since it's not a standalone fit without them.
We don't have more history or fitment detail on this one beyond what's in our records, so give the shop a call if you want to confirm it's the right unit for your application before you order.
