Dellorto vacuum port?
 

Does the dellorto carb have a vacuum port for ignition advance? I'm pretty sure the answer is no but I thought I'd ask before giving up on it. has there ever been one of these carbs that actually works? I've bought 2 cars with them on and had rides in 2 others and it looks to me like the stock carb is way better for power and mileage.

Nope. And, dellorto's I've used make more power and get similar MPG to stock carb.

Hmmmm... My Dellorto compared to a stock carb kicked ass. Although I have a YAW now (which is the stock carb tweaked a bit) that is dammm near close if not the same according to the butt dyno.
