It is a Schebler Model S. Don't get too close, the picture may catch on fire!  Jon.

Thanks Jon, Do you know what Makes normally used the Schebler, I don't remember seeing one anywhere ? From your comment, I take it that it was not the most reliable carb around?

I was just looking at those copper fuel lines Looks kinda 'Kludgy', don't it.  I'm glad the guys that designed these Great cars can't see what we do to them sometime.

Rick - lots of expensive cars (and boats) used the Schebler model S carbs.
The major problem when new was with the primary air intake.
Look closely at the drawing, and you can see two air intakes:
The primary is on the bottom right, through the banjo fitting, the secondary is on the upper left (aux. air valve).
When the engine is turned off, all of the fuel in suspension in the intake manifold and the throttle portion of the carburetor drops straight down and runs out the end of the banjo fitting (some models did not have the fitting, and the fuel just ran out under the carb).
And while the Schebler has some complexity, if you really want to see complex, take a look at a drawing of a Rayfield carb, or the float arrangement on the Johnson used by Cadillac.
The Schebler worked pretty well in its day (however, like most "automatic" carburetors, it doesn't like deathanol). Its biggest problem was leakage.
Jon.

For a short period of time, 1929 Packards were delivered with Johnson R carburetors. They failed within a short period of time. Does anyone know of any 1929 Packard that still has a Johnson R?

West - cannot answer your question specifically, but one Packard enthusiast who has fabricating skills wanted to build one several years ago. As you may know, the Johnson R was a zinc alloy casting and a "thin-wall" casting at that. Have never seen one in good enough condition to rebuild. However, this enthusiast contacted me to see what I had in samples, and I sent him several broken examples to use as patterns, along with a box of aspirin.  He called after receiving the samples, and we had a good laugh about the aspirin. A few years passed, and we talked from time to time, but his work schedule kept him from working with the Johnsons. Finally, he returned the Johnsons AND the aspirin (now outdated). Said since he no longer had the Johnsons, he didn't need the aspirin.  Jon.

I see one thing that makes the Schebler less complicated. It doesn't even HAVE a Choke valve.  I'm wondering how well that car starts on a Cold day ?  West, Sorry, It'll take More than Aspirin.

I would like to see them, I don't remember that thread. I noticed that All pictures are gone from older threads. I guess our Admin, that keeps his finger on the Delete-key, is At it Again.

Would like me to post them here or back on my thread? Here would be fine. Since so much is missing from your thread.

I've been searching internet, looking at various Makes of Carbs, that were available during the '20s, and I've come to Really appreciate the simple Detroit-Lubricator carb that Packard engineers desided to use.  The auxiliry-air-valve springs are a little difficult to adjust on the DL, but at least they are up where they CAN be adjusted, instead of buried down in the carb, like most Makes were.

When I was in my dad's basement over Thanksgiving, I found in an old box the remains of a Detroit Lubricator dual-throat that was used only on the 734 speedster. Have you seen the price on the repros?

, I found in an old box the remains of a Detroit Lubricator dual-throat Almost like finding a box full of Gold, isn't it ?  But by using the word 'remains', I assume there wasn't enough to restore, correct?

Hey, you don't suppose a little aspirin will help my Johnson start working, do you? More apt to make you forget and live with the fact it doesn't work.  Jon.

The last of the special built pedal cars will be going up for sale at the RM Auctions in Scottsdale in January. Built by the renown restorer Fran Roxas, this "Dusey" is truly is another work of art.
