I have a 302 with a mild cam in my mustang. I have a edelbrock 1805 650 cfm carburetor that I got used. I took everything out of the carb including jets and blew out and sprayed cleaner threw all ports and passages. Put all new gaskets in and a brand new accelerator pump when i put back together. The car will idle great and in high rpms it runs great. The problem i am having is a bad hesitation under low rpms. If I stomp the gas it goes fine but if I try to maintain a speed the motor chugs. I checked the vacuum and it seems to be good in that regard. Let me know if you have had any similar problems. thanks

Do you have the tuning kit with all rods/springs/jets?
I have tuned 5-6 of those. 3 for myself and 2 for friends. All but one ended up being replaced by holley DP's.
Anything much bigger than a stock cam will be very hard to tune. The secondaries just cannot flow enough air in my experience. This is why they came out with the 800+cfm version.
You may be extremely lean in the midrange if you are good at idle and wot.
The tuning kits need about three times the metering rod's available to properly tune.

Where are you located? Would you mind taking a look at mine?
I have a holley at my house as well but I need float bowls for that. I would rather use the edelbrock though because it is more a set and forget carbOriginally posted by BaronIf I dissagree with you, it is because you are wrong.

I had the stuttering problems too with my Edlebrock 650, turns out I had a bad fuel pump and a lot of junk in the carb that came out of the rusty fuel line before switching it out to a new one.
Have you checked the rubber on your fuel pump? Mine tore and was pumping less than it was supposed to.
