Weber information

[dirtbill]

Thanks for all the electrical advice, almost everything working now.

Does anyone have advice for manuals or other information on tuning triple webers, and where to source jets?

Thanks


Bill

A good info site, in my mind, is Teglerizer.com. He has quite a bit about Webers on it.

If you do a search engine search(Google) for Weber Carburetor(s) parts, rebuild, modifying, etc. you should pull up a whole bunch of sites I get most of my jetting needs from Pierce Manifols, but they are in California. You do have a major Weber supplier back in the NY area on the east coast...

The Haynes Weber manual is good. I don't know if it has specific info on triple setups. It also covers SU and ZS carbs.

Eric- Watched you run the slalom on Sat. Kind of like the old way better.

Thanks again

Does anyone know where to get good info about jetting the 32/36 DGV for high altitude?

Last year I did quite a bit of work on tuning the downdraft webers on my Porsche. 912 I have quite a bit of info for those carbs, but I'm not sure it's relevant to TRs. Best, I found, was to figure out what setups other people were using and go from there. Weber setup is a recurring subject for the Porsche 912 guys, but I don't see much about them here. Best to search the archives, I'd think.

You don't mention what model you're working on but I assume it's a TR250 or 6. Best advice in my opinion is sell them and go with SU or Stromberg much easier to maintain and equal performance results. You'll be happier in the long run.

As far as reference books, I like the old John Passini books but don't know what the in print/out of print status these days. They periodically get reprinted into a single volume so keep your eyes out for it/them. I also like the Des Hamill book on tuning Weber and Dellorto carbs from the Speed Pro series. Lots of good operational theory like the Passini stuff, but much easier to digest plus plenty of good practical tuning information and repair/maintenance information. Then there is always the Pat Braden Weber book from the HP series. That one kind of slots in between the other three (Haynes plus Passini & Hamill) books regarding the balance of operational theory, tuning info and repair. I have all four of these and out of the bunch of Weber books, if I could only have one, it would be Des Hamill's book.

As far as parts sources go, in addition to the ones that Sarastro lists, there is a seller on ebay that I have dealt with before for Weber parts, always came through, decent prices, wouldn't hesitate to do business with him again. This seller goes by Alfa1750, here's a link to his ebay store:

I've dealt with the first two of the ones Sarastro lists and would do business with them again, the folks at weberjets went above and beyond on an order that was misdirected by shipping company. I have no experience with the third one (Cars Unlimited) but I can't see anybody recommending them on here if they weren't decent folks as well.

There's also APT. They mostly seem to do BMC stuff, but have a fair number of TR bits as well and they do handle Weber parts. If you plan on running triple DCOEs on a TR6 and want to use an air filter, they sell some short (16mm) ram stacks that will fit under the thin K&N filters that clear the TR6 body work when fitted to 40DCOEs. While you should run some sort of ram stack with any Weber, with the DCOE40, it's more critical since the ram stack sleeve helps hold the aux venturi in its proper location. Here's a link to them:

These guys customer service is very good as well. On a Weber parts order for one of the parts, five of the six chokes ordered were correct, but the sixth was for a 45DCOE. I called them up and they overnighted me the correct part before I even had a chance to get the one shipped in error back to them. All done on faith, no charges with refund to happen on return of the other one either. That's tough to beat.
