Notes:

When ordering carbs from Amal, you can order by "ACK" or "PACK" number. "ACK" is standard carbs and "PACK" is premier. Everything above is for standard carbs. The Premier versions are jetted the same except for the pilot jet which is removable rather than the "bush" listed above. Amal builds premiers for Norton 750s with #17 pilot jets, and #19 for Norton 850s. As of mid-2021, the carbs are made of aluminum rather than a zinc alloy. Considering how much better the premier carbs are, we do not recommend or sell the standard carbs.

There is no PACK number for these but they can be ordered individually.
