NOTE: The first thing that I need to mention is that I do not know the exact year and model of 1960s motorcycle that this Dellorto carburetor came off of and I do not know all of the years, brands and models it will fit so you will want to look closely at the photos and description and make sure that this is what you will want and email me if you have any questions.
The ID # on the carburetor body is UB24B2.
This is a USED DELLORTO Carburetor that I am guessing came off of a Harley Davidson 250 SPRINT, Ducati or Benelli model of motorcycle. 
  *  The back of the carburetor has a piece broken off where the threads are for the air filter intake tube.
  I did put this carb in my Omni-sonic carburetor cleaning  tank and that is why it looks quite clean. I removed the float bowls and it is in good shape in there. The floats, needle & seat and jets look to be in good shape but I cannot guarantee that every one of them is in perfect working condition. The adjuster Screws on the side of the carburetor bodies are in good shape and they all turn and none of them are seized. The Slide, Slide Needle, Spring and Top Cap ARE MISSING and are not included. The choke plunger works good. This carburetor will need to be cleaned and adjusted before installing on another engine.   What you see in the photos is what you will get. The shipping and handling cost is $7.00 USPS Priority Mail to the 50 States of the USA.  (1.01.+)
