So I have an 82 and a 84 12a rebuilt my 82 did a mild street port all new internals but oil control rings and rotors , header ,stock Nikki carb but I've messed with every adjust on it so its prolly all whacked, it tries to start but won't . I can't seem to get my timing to light on the groove tried switching which coil I use as lead is there any way my rotors in on the wrong spot? Moved dist 180 degrees still not lighting on groove any help out there?
