Vacuum secondaries don't have squirters in the secondary barrels. That's why their called vacuum secondaries. Their not the same as a double pumper. In the picture it looks like there's no threads where the secondary squirter would bolt up. Is that correct? If so that verifies it's a vacuum secondary carb. If there is threads and it's drilled through it's a double pumper. Can you take a pic of the right side and post it? That'll prove if it's a vacuum or double pumper.
