312 keeps stalling

[Dan Smithwick]

My 57 bird will start and run for a short time then stall . I checked float level
on carb checked ignition and timing . Was running good a few months ago .
I don't think I have a vacuum leak . wonder if carb is bad . Any ideas .
Thanks

Does it do it just when hot or when hot and cold? Does it start up again right away ?
