Where do vacuum advance hoses go to?
I found the answer, the hose in front goes to the carb base and the one behind that’s closer to the head goes to the intake. The main one goes to the carb, it does acceleration, the rear one is just for idle, and is not so important

Both hoses and diaphragms are critical for proper operation. One is manifold vacuum and the other is ported. Check both diaphragms for leaks by pulling a vacuum on them. They should both hold perfect vacuum indefinitely. Manifold vacuum diaphragm is always the first to go.
