Have a look at ALL the photos where YOUR photo came from about EARLY production carbs, in the link I attached.
They have an idle circuit, like all FIXED choke carburetors have. If they didn't, they would have been a pig to drive. Gary |
LOL
I guess you could make prototype carbs without idle circuits, but you'd have to consciously decide to omit that. It's like saying "the prototype cars only had three wheels!" Uh, yeah, it's "possible" they'd do that, but that'd be downright unusual. ALSO if they made some that were really just testing prototypes that they'd throw on a flow bench and play with, then sure, they could omit all kinds of things. They could omit bolt holes if they wanted and hold things down with clamps. But to put a carb on an engine that's connected to a transmission and driveshaft and axle and tires that were sitting on asphalt? If you're going to not have an idle circuit, that's going to be a real pain to drive. |
Oh and in the "prototype inline carb" photos on that inline website, they clearly have idle circuits that include idle mixture screws and progression slots. *shrug*

Just sold for $7200, plus 5% BaT fee , and shipping.

In a surprising but related development, carburetors without idle circuits turn out not to be able to idle! It is easy to simulate no idle circuit on carbs with idle circuits. Just close down the idle screws — the engine stops running. Even more problematic you can not start the engine. Try it, it is a mind expanding experience for the uninitiated. Ed |
It is unfortunate when others would rather use defamatory comments than debate rationally, and come to an agreement on the correct answer.
The statement that says they "didn't even have an idle circuit", is completely ridiculous. The photo of the air horn clearly shows the two air bleeds per barrel, idle and main. The guy who wrote that needs to have somebody with a bit more knowledge than himself proofread for him before his writings hit the printing press. Perhaps if one reads about the operation of a device before shouting early production, since every fixed venturi carburetor has an idle circuit, whether it is externally tuneable like a Weber etc, or has fixed internal restrictions like many other factory carburetors. http://www.inlinecarb.com/uploads/3/...ine_manual.pdf Page 9/15 shows the idle tube. No idle circuit would have the engine completely die when airflow ceased to pull on the main circuit. Gary |
As far as "too much money" comment- that carb setup is very rare. If you are trying to reassemble an original Trans Am Boss Mustang racer, there is no more rare a choice. For those who seek originality, it is a great choice. Guess it is no more "crazy" then restoring any other vintage car.
