Great basic info in those Redline sites. I had never disconnected the throttle cable when tuning, I did it today and made a huge difference.

If you have Weber, you really should buy the book, as it explains how to adjust, tune, size, and install. If yours for example has the wrong size venturis, no amount of swapping jets will make it run perfect.

I'm making this thread more current... A/O Nov 5, 2016
Links below have be checked, tested and updated.
There is a little program available that gives preliminary jetting information too.
I have it on my website.
Own risk: http://www.airpoweri...car/jetting.exe
This link is dead. However, I found it at the AlfaBB forum. Scroll to the last post and follow the instructions. We may want to host it on Ratsun... just a thought.
All the above links are good... The Jason Gray and Teglerizer links are reached via the WayBackMachine
More useful tuning info for DCOE's. Much of it is applicable to Mikuni side drafts also.
The above link works (TeriAnn's Triumph Web Pages).
Here are some additional Links:
Weber 40, 42, 45 DCOE Carburetor Exploded View (other types available at site)
Original Weber Jet Specs (new carbs)
Pierce Manifolds, Gilroy, CA
Redline Weber, Torance, CA
Weber Carbs Direct, Hauppauge, NY
I believe that the book book referenced by Radim in his original post was Pat Braden's Weber Carburetors It's about $21 on Amazon.
The book referenced by ggzilla is Haynes' Weber Carburetors Owners Workshop Manual. Now about $40 on amazon.
Both books have a recommended jet settings reference.
From my Pat Braden book:
Page 169 listing conversion kits and their jetting (I've penciled in the missind info on the Datsun single 45 DCOE application. The added info sourced from ggzilla post above.) Keep in mind that this info was from 1988 do the newer DCOEs like the 45 DCOE 152 is not listed.
Here is page 167 listing standard weber jetting by carb.
From ggzilla's post of page 190 from the Haynes book:
I believe that the columns in the image above reference the following:
B. Carburetor type
C. Quantity of carbs
D. Main venturi
E. Auxiliary venturi
F. Main jet
G. Emulison tube
H. Air correction jet
I. Idle jet
J. Accelerator pump jet
K. Exhaust orifice
L. Needle valve
