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.

We have many of the PACK sets In stock - you won't find them For less anywhere than calling or emailing us directly.  They sell direct for even less than our eBay price which is lower than others.
