My completely stock 49 flathead was running great, but very rich with black \sooty plugs and exhaust extensions. Pulled Autolite carb for through cleaning and installation of quality NAPA kit. Now it still starts easily and idles smooth as glass at 5,500 rpms. However previously, from 10 mph in third gear, with easy acceleration it would pull away strong and smooth without the slightest shudder. Now it "lugs" in both second and third under the slightest load. Only "adjustment" we made after new kit was to the two fuel and air screws for nice idle. Whatt do you think is most likely the issue? Thanks for your input.

Did you make sure to reconnect the vacuum advance line that goes from the carburetor to the distributor? Proper spark advance is required for smooth accelerations. Have you put the accelerator pump link into the throttle lever? The proper hole to place the link in for most conditions is #2 (the middle one).

I'm thinking that a stock factory original 1949 Ford carburetor should look like this one. Three photos .......

Looks like the Holley 94 on my '52 F1. 1952 Ford F1 Pickup 1965 Falcon Sprint

Bruce is right. Here's what the 8BA looks like:

Gee guys, Thought I knew a little bit about these old Fords, and am still learning more. But I have no idea how a Ford script and #94 on the outside of a carburetor can affect the performance of an engine. Will be interested to learn. Thanks. 42OINK

Part of offering you worthy advice is knowing exactly what you have there. You did state the engine was 100% stock. Well, it isn't. Offering advice to fix a 100% stock engine can and often will vary from advice that pertains to a non-stock vehicle. I believe from what you'd been advised thus far, you be well served to locate a correct carburetor and have that rebuilt by a person that knows them inside and out. Charlie Schwender gets my vote for that service. He may even have a carb. for you. By the way, you state the engine idles smooth at 5550 rpm. That's idle speed?

It sounds as if the carb has the incorrect main jets, for your purpose, making the off-idle too rich.
