You're running it lean. The glowing header is a dead give away. Keep running leaned out like that and see how long that engine lasts. Make sure ignition timing is correct. (Right side, inside fender, near to firewall) connect that to a ground. THEN check the ignition timing. Distributor may need turning. Either or, timing is off BADLY or you're running lean.
