    i have got an 82 fj60 with a 32/36 weber carb and before i installed the weber the PO had some old holley that he had rigged up ???, but anyway the question that i have is on my vacuum advance on the distrubutor there are two vacuum ports on the vacuum anvance and the PO once again installed a T and hooked them together and then hooked it to the port on the base of the carb and so when i installed the weber i did the same. if i am not mistaken doesnt one of the ports on the vacuum advance go to manifold vacuum and one go to the ported vacuum on the carb? if anyone can enlighten me on the subject or tell me how to hook it up properly that would be great.
    p.s. the PO also unhooked most of the emmisions and got rid of most of it.
    thanks in advance

    The T is correct. The outer port is for the Hi altitude compensation system. It adds advance when you are up high. No problem with a T or not using that port as long as you reset timing.
