A VTV, and thence to the choke breaker. Not needed unless you are doing a resto or a re-smog.
I'm researching ported vacuum, for FJ60 distributor vacuum advance, for upgrading the ignition system in my Federal spec '76 FJ40 (11/75 build date). My carburetor has a port to the front of the idle mixture screw in the same location as shown in your photo immediately above. Where does the vacuum line run that exits the right side of the photo? To the distributor vacuum advance port?I think this is what is being described above?...Pics from my first carb rebuild ('76) and installed to verify it would run on my '77 FJ40.

Oh, I'll take for granted that you have the vac advance on your dizzy hook into the egr cut port, as seen below.

HTH...
I think I may have answered my own question. I'm assuming this is the same engine as in the photo above. I've been reading more about the EGR Cut Port as a source of ported vacuum but haven't been able to confirm this would be a good port.FWIW - I purchased an '86 FJ60 2F to rebuild and install in my desmogged '77 FJ40.

There are only two vacuum lines on mine. One from the vacuum advance on my Trollhole Dizzy to the EGR Cut Port on my base of my OEM '77 Aisan carb. The other is from my choke breaker to manifold vacuum.....The vacuum hose spaghetti/smog mess is now residing in Cali.
Thanks! I've got two complete kits for installing relatively low-mileage (125K to 175K) FJ60 distributors into my '71 and '76 FJ40s: distributors/coils/igniters/dented side covers/side cover gaskets/distributor covers (optional), plus new parts on order from American Toyota: distributor caps/rotors/dust seals/O-rings. Do I have to worry about venting the distributor caps once I'm done?Yes, that is the ported vac fitting on carb base. Connect it to a vacuum advance dissy. Do not connect to a vac retard dissy.

Yes, that's the only option.For the distributor vacuum can I tee into the line that runs from the port on the carburetor to the vacuum switching valve?
