IH: Carburetor, Intake Manifold & Exhaust Systems - Sub-01A

E65 uses DC-12. L65 uses DC-6. ¹⁾

Here's the early 1957 DC-1 Linkert without idle airbleed.
It can be spotted by the short brass tube on the side of the body while later versions have a taller tube.
It also has a fitting to connect to the idle air passage hole visible in the picture above the short tube.
Other identifiers for 57 are no patent dates on the float bowl with a 90° elbow fuel inlet.

There is a brass baffle in the DC-7 float bowl on the left in the pic below. The DC-12 (right) does not have one.
The baffle helps arrest an rare-ish annoying Linkert trait.

If your moving at high speed and you grab all the binders you can in order set up for a tight corner; ⁸⁾
The fuel sloshes to the front of the bowl opposite of the bowl vent tube.
As you stand the bike back up and peg the throttle (wot), the fuel now sloshes over to the opposite end of the float chamber.
(where it enters the top of the vent tube and exits the carb (spraying the rider, you will smell it).
In extreme cases, if your hanging off the right side of bike, you can get a face full of hi-test.
