Reduced float levels in both bowls

I'm thinking you need to raise the front float..

Bob... Maybe that did not make sense?
There were pin wholes in the floats. It would fill up with gas on hard acceleration or decelleration. And even if the car was started on a hill, the float would also fill up gas and sink in the bowls. I did not know why. During regular cruising the car would cruise fine but we could not get the carb to idle. I guess it has something to do the lack of gas in the bowls? The carb is a service replacement unit and had a plastic floats at the time. Took the carb to our speed shop and the replaced the plastic units with an aluminum (or metal looking) unit. Problem solved. Does this help?

So you replaced the bad float and it still does the same thing ??? Lowering the float drop puts less gas in the bowl is all I was saying..

How about replacing the carb with one you know runs well to help to isolate the problem.

Changing the carb is an option I considered. Just trying to avoid doing all that plumbing!!! Will try increasing float level today, if that doesn't work, then another carb...

Sheeeesh, raise the floats, lower the floats, raise the floats, lower the floats...........
I'm tired. You could raise OR lower those floats all day long off stock setting and you probably wouldn't notice any differnce in the way the engine ran. If you have a hard time setting them to stock setting, that's an indication they're sinking, otherwise just set 'em stock.
Then go back and run that vacuum test. Does it idle ok with your foot off the brake???? So far you've only said the car runs bad when you step on the brake............

just trying to help
