you can always try to set the carb control arm / roller at different locations by unscrewing the bolt under the fw….do some testing
as to electricals…why not go all the way for peace of mind 10 miles out. Chineese coils are cheap a few feet of metallic 7mm & boots will solve any problem with old wires/coils
Belden 7mm metallic ignition kits for old cars work great , not expensive per wire & boots are factory assembled 🙂
