Scott,
I agree with Ohmess. Back in the late '70's when I installed triple Weber DCOE 40's on my '73 CS, I bought a 'vacuum tool that fit over the intake of a carb, (available in that era, not sure they are still available), and set out to get the air intakes all balanced. From there, I proceeded to test out a few jets, etc. Fun work if you want to 'learn' about carb tuning.
Actually, I have four paper back books on Weber Carburettors. If you decide you'd like to do this, I'll loan them to you for 3 months, cost of shipping both ways, and an assurance that you'll return them to me in the same condition by ~11/1/17 is all I'd want. Two are by John Passsini - 1st is Theory , and 2nd is Tuning. Approx 60 and 115 pages respectively. Then, a Guide to Tuning Weber carburettors published by Borg Warner in Australia, finally a 190 page Hanes publication on Weber Carburettors - Tuning -Overhaul-Spec tables-Popular Types to 1979. Since all of these were printed in the early to late '70's, they may no longer be available. IF they are, I'd suggest you buy them as a critical part of the long term library for your car!! But - available for loan if you prefer that approach.
While I'm typing away, a couple of other comments. If I recall correctly, I sold you some window motors last year. If that is correct, I hope the windows are going up and down properly.
Finally, commenting on you Forum name: I finally did something I've been wanting to do for a long time this morning. I did a Google search to confirm my suspicion that my wife and I own two of your products made for travelers. I've been using my ScotteVest for about 4-5 years, and I liked mine so much on the first trip to Europe that i bought one for my wife before our next trip. I think she's had hers for a least 3 trips. We wouldn't travel across the pond east of us without one. The only drawback for us 'old' folks (80 and 72) is that there are SO many places to store items when we are out and about that we sometimes forget exactly where we put xxx and have to go through 2 or 3 pockets to find that item we want!!!! GREAT product, and our compliments on your development.
Cheers,
Gary--
PS: Nice pix of a portion of your e9 and I assume your wife on the corporate page.
