Changed carbs back to the Edelbrock and the problem went away. There is still a slight bogg in the Eddy, but it's because of the secondaries not opening soon enough. But at least this tells me that the Pro Systems carb has some trash or something going on there. It's very strange why it's running great now. Like I said, chasing a ghost!!!
