hollley 570 street avenger running rough
« on: November 11, 2010, 01:55:16 pm »
I have a holley 570 dual feed double pump electric choke that boggs down when I take off when it is warm or cold. Is there something easy I can try to fix it or is it time for a new edelbrock 650cfm???? I have a 350 that I'm gonna put headers and an exhaust on it next week.   Thanks

If it is a Street Avenger then it has the quick change secondary spring kit. It should have also came with a couple of springs. For trucks you have to use the heavy spring so the secondairies open later.
