Pedr,

I see you have a manual laying on the bulkhead, if it is the TM 10-1531 that I am looking at now ,then your carby is different to that shown in the Fuel section. It is described in there as a Zenith series 29, no mention of a Carter, but my book is dated 1942, so maybe that came later.

A point worth think about is that the carb may look like a correct one, but could be set up/ jetted for a completely different engine, for example, I am rebuilding a Austin 900cc 4-cyl. engine for a customer, he brought in a brand new carb to use on it, externally and bore size is identical, but something made me check the specification number stamped on it, seems it is actually for a 3,500cc 6-cyl. engine. As the carb on your Dodge does not quite line up with the bulkhead there is every chance that this carb was not intended for that vehicle and this is possibly why there is a flat spot.
