4150 Double Pumper Question

I am not much of a tuner so I am hoping you guys can help with some suggestions. I have a 600 cfm 4150 Double Pumper, Mechanical Secondary, Manual Choke Holley on my Model T Roadster. The motor wants to stall in stop and go traffic when I apply the brakes. Especially true if I really nail the brakes, doesn't stall if brakes are applied easily but stumbles a bit.

Other than this it runs fine. Tranny is a manual 4-speed and the car has manual brakes, no power anything. Stock freshened up small block Ford 5.0 HO roller cam motor circa mid to late 1980's. Low compression 8 : 1.

I hate to start screwing around with the carb, cause like I said I ain't a tuner. But seeing how I built the entire car myself I ain't skeered either. Just don't want to take two steps forward and four steps back.

Thanks in advance

Sounds to me like the float level may be set too high.

I agree that was my first thought. Check your float level. Gas should just seep out the hole .
