14.6 volts cold at 1500 RPM is pretty good; may be just a tidge high but nothing to worry about. Di you test this voltage at fast idel (1500 RPM) or low idle (700-800 rpm)? If this 14.6v is at low idle, re-test at 1500 rpm and see what you get.
Actually the idle was already on the high side 1500 or so. We didn't get a chance to lower it as this was the first start after a cam change, head replacement and a switch to carbs. Maybe it will be lower at a lower idle. Thanks for the resonse
