well I thought some of you all might have a I dea to help getting my Cougar fine tuned. The problem I'm having is this: When I give the engine any kind of quick rev it revs beautifully untill I let off. Then it bogs for a second before returning to normal idle. I have an edelbrock preformer 600cfm carb, I'm not sure of my jet sizes but maybe that's not too important. It's been doing this since I took over the car and rebuilt teh engine 3 years ago. Any ideas? Need more info?
