The problem is that 235s and the "B" that came with are made to work on port vac. with no vac at the distributor at idle I understand that I made the wrong choice on a YF 4480s its made for the newer 230,260 6s that use manifold vac at the distributor what I'm asking is if the 2100s all have port vac or manifold vac and is there other YF #s that are port vac.?
