Hi Chris, I just did this with 6 DCOEs this last winter/spring. I needed a soft wire brush on my buffer and I bought a bead blasting cabinet. I got some small hand SS brushes as well. Finding the specialized tools for these carbs is very difficult. I could not found a seat reamer but I did end up getting a tip on antoher way to fix my problem. I had numerous linkage and intake manifold pieces to do as well. Mine needed a lot of work so I ended up soaking them in a 5 gallon pail. The 5 gallon size was supposed to be the "industrial" version. Bottom line, I don't think you'll find a version of a cleaner out there that's as effective as the stuff from days gone by. Pierce Manifolds uses the bead blast/ultrasonic combo. I ended up masking the hell out of my carbs, putting on all the cover plates with the old gaskets and bead blasting them. It worked very well and they turned out beautifully with zero internal penetration of the glass beads. Mine had a lot of exterior corrosion. I've done others that did not and the bead blasting was not needed. I'd try to avoid the bead blasting if not required. The current version of soak cleaners don seem to brighten up the metal like the old stuff did. Other than that I had all the screws, washers etc. re-plated and replaced the idle mixture screws plus some other items out right. All the plating of the carb, linkage and manifold bits was about $100 and tedious to keep track of while dealing with the plating company. I've attached some pictures. As you can see, I started with a big mess. I used spray lithium grease for the ball bearings. You could just send them to Pierce Manifolds and enjoy your winter in front of a fireplace instead of standing at the blaster cabinet and soak tank ;>) Bob S.

Thanks Chris. They did turn out looking nice and I have yet to put them back on the Lambo but soon I hope. I was half way into the project when I started looking at big utrasonic cleaners and I just never pulled the trigger. I think Craig, also on this post, sounds like he may get one. He and I as well as some other helpful folks on this site collaborated on a Pertronix distributor conversion earlier this year. He was very interested in my Weber restoration as well. Craig is Mr. Muira and has an astounding collection of technical info on those cars. He may well know the serial number and production date of every tire ever mounted on a Muira. ;>) He IS that detailed. Bob S.
I use Berrymans B-12 Chem-Tool in Gallon Pails in a medical ultrasonic cleaner-which works great on my pistols also... as to the lead galley plugs, which Rifledriver correctly notes ought to be replaced as part of any REAL carb rebuild/overhaul, the best, closest, real world substitute is-if you can still get it here in California-is #2 lead, Duck Shot. It is as if it were made for Weber! Be they IDA, DCN, or DCOE.... used it on all of them, NEVER had a failure, leak, of cracked housing. Extraction tooling, is of course the key... "are you a toolmalker" is an important question to ask oneself prior to embarking on this job-seriously. It is not for the novice, no mater how ambitious. Ask they guys at Pierce if you don't believe me...the housings are really getting scarce...
The Berrymans Product in the 5 gallon pail with the basket in it is what you want, regardless of the cost. It will disolve anything fuel related within the carbs. The stuff is pretty caustic and will leave an odor on your hands that will remain for days even if you are just handling dried parts that have been soaked in it. I recall once MANY years ago I thought nothing of dunking my hands into the container and handling the immersed parts. I recently did a set of 48IDA's and found the mild acid that is used to wash aluminum wheels and trailers at Truck washes leaves the aluminum with a bright appearance. I bought a small "Water bottle" filled with it and used a toothbrush to scrub the parts, with gloves and lots of water.
With an ultrasonic cleaner. Worked pretty well. I used a special cleaning solvent made for carburator-material Image Unavailable, Please Login
