I've got a 53 ford customline with a inline 6 ohv and the stock carb. My problem is when I hit the gas fast it stumbles and then wants to die. When I ease into the gas its fine. I've checked for vacume leaks and found none. I rebuilt the carb and replaced the power valve. Also at idle I'm not pulling any vacume at the carb, untill I rev it up and then I only get about 10 pounds. Which make my wipers not work. I have the original glass float bowl if that helps any. I'm not sure where to go next. Thanks in advance.
