Rebuilding Weber 32/36 DGAV 33A Carburators

[Ohmess]

Here is a update summary of what I learned rebuilding the Weber carbs.
1. I wish I had injectors as previously mentioned.
2. This forum is extremely valuable and I appreciate all the help I received. I reviewed all the posts about Webers and contacted a few members. If I mention names, I might missed someone - thank you for all the advice.
3. I am not sure how this car ever ran before the rebuild as the main jets were way too small. The mains were 125 and 127. The primary idle jets were different between the front and rear carbs (52 and 55). After the rebuilds, I had a very hard time getting it to run using the old jets.
Per contact with a Weber "expert" the normal standard jetting is:
Main primary 135 secondary 140 (mine were primary 125 secondary 127)
Air primary 160 secondary 170 (mine were primary170 secondary 175)
idle primary 55 secondary 50 and he confirmed that the secondary is smaller.
4. I added several tools to the collection such as AFR meter, Carbmate, and Air Flow Synchronizer which were all extremely useful.
5. Now the car is very drivable and AF ratios are good. I am planning one more change to try to clean up the cold start and idle just a little more.
Once I have the final jets in and confirm the AFR throughout the RPM range, I will post them.

Dan - I would not change things in an attempt to improve cold start/idle. My car runs like crap when its cold; I just wait for it to warm up.

Anything you do to improve cold operation will mess up how the car runs when warmed up.

Thanks for this information. I have already bought a couple more jets and will try them. If they don't help, then I will go back for drivability only. I really do appreciate your response.
