Need to replace my Dellortos with something more reliable...and soon. Don't want Chinese manufactured (Empi, Interco, Webercarbsdirect, etc.), but original European. Can anyone direct me to someone who might have a pair for sell...new or used?

Thanks for the links. I'll call them tomorrow as I didn't see 40 IDF carbs for a Type 2 2.0L on either of their sites.
Would MX carbs work?

You haven't said anything specific about your Dell' or about your engine as far as performance parts are concerned.
What Dellorto's do you have ?
And, what's the problem......
There are a few 40 mm used weber carbs available in the classified here.
40 AND 44 MM Webers are about the same as 36 mm Dell's. and need to be jetted accordingly for your engine
you will spend between $400.00 & $800.00 depending on usage vs new and
possibly end up in the same place without posting info on your Bus.
I run 40 mm webers on the engine in my bus that develops over 100 hp
and have probably $ 300 in parts from jetting them from lower HP engines.
So in the end you will possibly end up being close to what you have now unless we know more about your engine

I've got a 2.0L engine. The Dells were on the bus when I bought it and are 40's. I didn't know that I'd be looking at something different in a Weber. What would be the equivalent if I've got 40 Dells? I can't tell you offhand what the hp is on my bus, but those Dells deliver quite a bit of power. It's possible I won't need to find an equivalent with the Webers; maybe I can ratchet down without too much loss of power? Like yours, at 40 mm?
The Dells were leaking gas through all four of their "progression holes" (one for each barrel) and I had them rebuilt not all that long ago by a guy who advertises on here. He had problems plugging one of the holes and eventually swapped out my carburetor for one of his. The short of it is that when they came back, one of the progression holes continued to leak gas! I mean like right out of the box! Not sure if it was his carb or mine, but he claimed that it wasn't leaking when he shipped it off to me. He said he would fix it, but I lost confidence in him (he had the carbs for weeks) and couldn't afford the lost time it would take him to fix it. Unfortunately, there is no one here in Seattle (hard to believe, but true) that can or will work on Dells, and my mechanic has repeatedly told me to get rid of them because they are ruining my engine.
That's my story. I'm tired of dealing with the Dells. The guy who rebuilt them couldn't say enough about how superior they are to Webers, but it seems they have this Achilles heal where these internal progression holes that are stopped with a lead plug corrode over time and leak gas into the engine. Doesn't sound like a superior design to me?
Obviously need to look into the classifieds here. Thanks for your input!

If I were a betting man I would bet it's time for you to seriously think about
saving up for ALL the F.I. parts needed to put the engine back to stock.
Ship me your carbs and I'll fix them for ya' or may also buy them.

Right now, given money availability, I will have to go with a pair of Webers. I'm intrigued by your offer. Once I get them off the bus, I may consider shipping you the one that's leaking or both for you to consider selling. What do you think they're worth rebuilt? They're basically newly rebuilt and clean, except for this one ongoing leak.
So, how do you fix these progression holes? Do you plug them with lead or with Loctite? Do you have a lot of experience working on these?

Okay, here's what you need to do.
1) Save your superior Dells and send them to Blackline Racing
http://www.blacklineracing.net/index.html
Read about them here:
http://www.thesamba.com/vw/forum/viewtopic.php?t=548058
They are what used to be known as ACE. Dave Hogarth has been there for several years and is a God when it comes to Dellortos. Last year I had a customer with a leaking 40 DRLA and Dave fixed it right up.
2) The next choice would be to buy a new set of Weber 40 IDF's from Aircooled.net.
http://vwparts.aircooled.net/CB-Performance-Dual-I...rb-kit.htm
Choose T4 and add the carburetor setup option which is well worth the money. The kit will include the superior CB Performance linkage (better than Redline) but you'll want to buy velocity stacks. Tell them what size engine you have and they will jet them correctly plus clean the carbs and set the floats. When you get them they will work pretty much without a lot of tuning trouble.

The guy offered you the chance to get them right for free, and you are denying him the chance to do so??

Yepp Gary is correct on sending the dells to blackline racing since I have only limited experience building them.
Hold on! I need to take my socks off to count how many I have done over
the last 4 decades. 
seriously, all I care about is that you have a good running Bus
As for "Aeromech" (Gary) next time we are in the blackwatch I will NOT have a drink in your honor.

I know all about Black Line Racing and Dave Hogarth! Yes, great guy and incredibly knowledgeable. I will indeed send him the one carb that still leaks and then probably sell them online? The problem is that my mechanic doesn't really know Dells and I don't think he knows how to fine tune them, so going with Webers is probably better for me in the long run.
As for your suggestion #2, I followed up on Redline and they have a VW conversion kit (40s or 44s) that retails for something like $760.00. I already have the CB Performance linkage. Any reason I should go with aircooled.net instead? Does Redline do something similar to their carb setup service?
Interesting that you suggested the 40s. Many have told me I wanted the 44s, but my mechanic also suggested the 40s. I see on aircooled.net's site that they also push the 40s.
Thanks so much for a great post!

Those are 40 IDF's from Aircooled.net pictured above on a 2L hydro valve type 4. They run very well. There is another place you can buy the Webers and get the tuning service. DRD Racing Heads in Los Angeles. I've done business with them before and would recommend them. I would not recommend Redline.

I meant to mention your picture: that engine is a thing of beauty.
Two follow up questions: why do I need the velocity stacks? and what do you have against Redline?

I use a synchrometer to adjust the carbs and you need the velocity stack to seal it to the throat of the carb.
I've called Redline for answers before and I didn't like their tech support. I've also purchased Weber kits from them before and found the linkage crappy and not worth buying. Good linkage makes a huge difference when making an engine run well.

Well, I've got new linkage (bought from CB Performance when I had the Dell's rebuilt 6 months ago). The question is does Redline and CB Performance both use genuine European Weber carbs? Are they presumably getting them from the same source, i.e. Spain or Italy?

Spain or Italy?
Just a guess but I'd say they both sell Spanish Webers.
One thing that's important to point out is that these new carburetors arrive assembled but dirty and sometimes with incorrect float heights. On top of that, in order for them to run well, they need to be properly jetted. The value in having a place like Blackline Racing or DRD set them up is high. These people have experience and know what works so when you get them there is no "guessing game" to go through. $80 is less than two hours of my shop charge and money well spent. Redline won't do anything for you except sell you a new carburetor.

This is helpful info. I think you've made a good case for going with either DRD Racing Heads or aircooled.net. I'm leaning aircooled.net.
