Thanks for the reply. 12 was with the old carb, 6 with the new one. Have jetted down to 74/84s and plugged metering bowl leaks finally. Car runs appreciably better. Like Ray said, timing is set with Vac plugged at 12-13 initial, 34 total. Signs that with Vac attached I am getting a deal more. Simple fix is I am going to a new Crane set up and mechanical advance.
