Carb jetting

for Amal, Mikuni, Dell'orto, Weber, etc.

Please send corrections, comments, additions, etc. to mason at postdiluvian dot org.

These jettings have been culled from various sources - some are from carbs that I jetted, some are from carbs that I took apart, some are from shop manuals, some from people who have worked them out, and some I just found on the net. I do not mean to plagiarize anyones work, drop me a line if you'd like an attribution or don't want your secrets posted here.

See the end of this page for some related links.

* Slide: 0.050" filed off the bottom of the throttle slide.
** Use smaller needle jet (P-6 or P-4) to lean out midrange if it's too rich. This will also improve the mileage.

Note: The only Amal parts list I have that covers Concentrics
gives the same part number for the above three needles, although
this doesn't make sense.

Other Notes:
--Of course, in addition to the basic part numbers for the jets,
each is available in a number of sizes.

--Although most Amal sheets for the RN, TT, and early GP call for
a 3326 main jet, other sheets list the 376/100.  Nicholson's book
says "The monobloc and T.T. type main jets can be used in the
G.P. carburetor."  The jets are physically quite different in
appearance, so I can only speculate that since the main jet is
submerged well below the top of the fuel level, only the internal
bore matters.  Perhaps they developed the 276/128-style jet for
the then-new Monobloc, discovered it functioned fine in the other
carbs, and then standardized on it.

--Needles for a variety of special applications also were
available (e.g., alcohol fuel, the Norton 850 and Triumph T160,
etc.).  Listed above are only the "standard" needles.

--I don't have a parts list for Mark II Concentrics.  If someone
has this information, it would be nice to include it in my final
table.

Amal 375 Monobloc
Amal 376 Monobloc
Amal 389 Monobloc


Transcribed by Dennis Wright - scorpion at cdi.com.au.

A note on Amal part numbers: There is some overlap between the part numbers for Amal carburettors and Amal carburettor parts. For exampke, Amal part number 389/063 is a 389 (Monobloc) carb for "Villiers 197cc 1962-63; 9E Super Sports". It's also the part number for a Monobloc needle. 928/076 is "obviously" the part number for a 28mm Concentric carb, but it's also the part number for a velocity stack for a Concentric.

Amal 375, 376, and 389 Monobloc carbs should have a date code as well as the part number stamped on the flange. The date code will be something like "11 65", meaning November of 1965.

There are not many foreign (non-British) bikes represented in this list. I suspect that German, American, Italian, etc. applications are covered elsewhere.
