Car in question is 1963 automatic, 110, coupe, when car is cold ,even letting run for a few min. when I engage the transmission car cuts off, it does this about 3 times then runs good. New plugs, new plug wires, points condenser, rotor, cap. I think problem is in carbs. because I have set idle a little fast to keep car smooth at stop. Any Ideas? Corvair Driver Garland
