My 74 was running fine today and then gave her some gas in second she started to bog down bigtime.
It got worse when I tried to move from a redlight, started breaking up real bad,almost didn't make it home.

Any suggestions welcome.

 

I'd check float level, pump pressure, fuel filter, and possibly ignition. Is the carb in good shape? If it's the foam float and an old one, it might be soaked and not floating.

 

For the prob to come on so quickly and getting worse, I'm thinkin' fuel filter.
Although it very well could be that there is an issue with the float/needle valve.
Do you have a mechanical or electric fuel pump?

I'd try the filter first.
