Ported or manifold Vacuum to Dist.

Crazy you mention that but my original HP273 AFB carb only has one vacuum port for the distributor. Manifold vacuum. I should snap a picture tomorrow.

Yes, do. What year? I'll check my '67 FSM for that carb.

I have found the '64 Tornado 230 used manifold vac. At least that's my conclusion from the distributor specs in the FSM.
However it did have PCV. ;)
