So Ive been reading up on weber carbs since I just bought one. I have found lots of usefull advice on most everything, except locating all of the jets/airbleeds/etc.

I seem to remember way back, seeing a picture of a 45DCOE with the top end removed and aarows pointing to everything listing what goes where.
While most of it I can figure out on my own, I thought that for other weber noobs an ultimate all encompassing weber sidedraft thread would be helpfull.
I plan to start such a thing if there isnt one on here already, but before that I would like to get some pictures together and make sure all my info is leading people in the right direction.


So, to start I just wanted to ask if there was a picture that locates the airbleeds/jets/etc needed to tune a weber 45DCOE.
If no one posts one here, Ill take one myself.

Once everything is located, I plan to pull the jets/etc. individually and take pictures, hopefully being able to instruct people how to identify/read the markings, and show what goes where and how the pieces fit together.......
Just something that would just give someone more confidence with their carb, without/before buying a manual (something I would do if it wasnt hard to find locally).

Anyways, I will use this thread to compile pictures/info. Once the pictures have been made, and everybodies tips/tricks/jetting has been shared I will put it into a new thread hopefully covering everything to do with a weber sidedraft.

I ask that we take this step by step and dont get ahead of ourselves, working our way up from Jet locations, to initial setup, to getting the car running, tuning, and then little tips/tricks and troubleshooting.
I believe that once its finished, a very helpfull thread can be made and the future weber carb owners will have a good place to start.

Thanks in advance, I cant wait to see what we come up with!!!!!
