Hi Lynn,
I read some time back where a builder jetted a DCOE to run with the choke on at sea level and used it to lean out the mixture at altitude by backing off the choke. Do you have any knowledge of this, or other methods of variable mixture control for Weber carbs in aircraft?
Thanks for your comments, Dave McC

There are many Weber books that show all you need. I have been using one since 1980, if you have any problems.
