So I finally got my build to run, but found my idle was pretty high. Initially it started idling around 3k then when I revved a bit it stuck around 4-5k. I ended up lowering the idle adjuster pretty much until the bolt no longer touched the stop. It’s currently idling around 1.5-2k.

Would this be a TPS issue or choke cable issue, or potentially something else?

Have a look at the position of the ratchet clamps on the rubber inlet manifolds. I had a similar issue and it turned out that one of the clamps was turned in just enough to prevent the linkage from dropping all the way down.
