today i spent most of the day rearranging my holley 670 street avenger...here is the problem the car runs great when you accelerate but when you drive along noramlly(city driving)about 1200-2200 rpm the car seems to sputter and choke alot.i replaced the 670 with a holley 600 dual line vac secondary carb from my wifes 65 mustang and it ran like a top through the whole rpm range.the 670 does great "WAO" but does not have what i would call drivability.any ideas??
any help would be appreciated i truly love to enjoy my cobra but this is starting to suck.
thanks john b
