The new vacuum advance made the spike go down to around 15:1, so it helped, but I'm looking for that momentarily rich dip that Schurkey mentioned. I did adjust the idle down to 13.5.
I'm out of town the next couple days and my son is using the car as is daily so I'll jump back in later this week. According to him, it's running much better today but IMO the bar was low. I'm hesitant to modify the carb by drilling out passages until I've tried everything else.
