I have been using modified zenith carbs for my 2.7. A while ago I obtained a set of webers however I just haven't had time to rebuild them til recent. They were pretty dirty however they are cleaned up now.

When I was trying to set up the carbs, I found that my accelerator pumps were spraying different amounts. Here are the amounts
Cyl 1- 0.9cc
Cyl 2-1cc
Cyl 3- 0.5cc

Cyl 4- 0.9cc
Cyl 5- 0.5cc
Cyl 6- 0.4cc

It is clearly easy to adjust the amount on one bank however I how can I between the different individual cylinders?

Also, what is the proper amount they should be spraying? I believe it is 0.5 +/- 0.1cc on zeniths however not sure on webers.
