I Don't care what Edelbrock and their corporate lawyers say. They say a lot of things that aren't true, like the rpm airgap won't fit under my hood.

I see the OP found his issue but I had a new edelbrock 650 with a stock ac delco fuel pump on my car and the pressure was overwheming the float system in my car, upon further reading I found the edelbrock carbs need lower fuel pressure than the typical 7psi the holleys and others utilize. once I installed a regulator with gauge and adjusted it down to 4-5 the issue was corrected. Ive seen this advice mentioned by others like jebbysan multiple times so I know im not the only one. The stock replacement carter style pumps do vary from unit to unit as ive installed a few on my car and ive had to adjust my regulator for each one.

Got a plumber buddy who might solder it up for you for a few beers?
