1992 Triton resurrection

Should we know what the intake PLUG is all about (I am Weber ignorant)

That plug is for a coolant passage that the Mikuni uses for its auto choke, which the Weber does not use, and adapter plates may not block it completely/reliably, so it's recommended to put a grub screw in there just to be sure.

This is what's going on in that picture. The bit you can't see is there is another pipe that needs to be blocked off toward the back.

This is the Chinese made Weber 38/38 clone hooked (mostly) up and running really well. Full confession: we used to do this back in the 1980s on our Chrysler Galants (maybe they were called something else in the US like a Colt or something). The mikuni carbs are fine when they are going but really hard to fix, where a Weber is a much simpler device and adds a few precious HP.
