Midwest Mopars in the Park - Farmington Mn.

Well I didn't make it today. My car runs great at idle and while accelerating (even just barely accelerating or WOT) but trying to drive a constant speed or hold a certain rpm with the clutch in and it sounds like its missing and it stutters. I tried jetting it up, checked every plug and plug wire with an ohm meter and adjusted my floats, jets, and checked for vacuum leaks. Only thing I didn't do was check timing so I'll try that tomorrow morning. If that doesn't work I won't be bringing the Dart :/
