—————————————————————————————————————————————
This resource is under development, ALL additions and corrections WELCOME, in fact its a MUST!!.
—————————————————————————————————————————————–Carbs used on competitor models are shown incase you come across one at a swap meet or auction. You can then compare nozzle, venturi, and hole sizes against the original specs for your Indian carb. This page is not (yet) intended as a rebuild or tuning resource – just serves as an identification and comparison guide. It mainly came about with me having to identify over thirty carbs in my parts pool – hopefully it will help others too. Schebler Carburetors were manufactured in Indianapolis, Indiana, patent applied by the Wheeler-Schebler Company in Oct 1902.Notes: Drill size numbers on two hole idle (Idle2) systems are annotated (fl)=flange (in)=intake, one hole idle (idel1) on the Deluxe models are plug number sizes.
Schebler Models G, H, C, AM – Carb ID numbers (ID #) are stamped on the upper body casting.
List excludes AMX 6 and AMX13 as used on some Indian racing specials.
<Above Left is picture of a rare AMX12 racing carb,, Above Right, a rarer AMX13
For H Series Only: The sNozzle column is the size of number drill used for cleaning spray nozzle, The aValve column is used for size of leather air valve disc. (see photo of operation for a Model H)

Amal
British designed and built Type 6 (early) Amal Carburetors where used on some Chiefs ’52-53 (Police excluded),
Vertical Scouts and Warriors from 1949 to 51 (I think!). Note the 3 bolt linkert manifold to 2 bolt amal adaptor.
From the late 40’s through the early 70’s and beyond most all British, American, and European carburetors have been of similar types. Whether its an early Amal Type 6, or a Linkert, or a late Amal concentric, they all function basically the same. The major difference between American carburetors and those on British and European bikes, is that for the most part American carburetors have used a butterfly valve rather than a slide/needle to meter the air/fuel above idle.

Zenith
At this time I have very little knowledge on the Zeniths. I believe they were used on some 36/37 fours, i.e.. the upside down fours, particularly the sports four (dual carb). please contribute if you can.
Hedstrom <under development>
This is a variation (perhaps racing?) of the Hedstrom Hendee carbs as used in the early Indians
