As I said, it's a fuel delivery problem. You proved that when you blocked some intake air and it ran better.
You found that fuel is getting to the carbs properly, so all that's left is the carbs themselves. If it runs better with the shims than without, that's more proof that there isn't enough fuel in the air/fuel mixture. Same with running better with the enrichers open.
