The 1969 Bronco is the older, simpler counterpart to the 95's EFI complexity — a 200ci inline-six with a carburetor instead of a computer to argue with, which means the troubleshooting is mechanical and tunable by hand rather than diagnostic-code-driven.
The carburetor conversion to a Weber 32/36 progressive is the main mechanical work so far. The Weber 32/36 is a common, well-supported swap for this engine family because it replaces a tired or mismatched original carburetor with something that has better parts availability and a progressive secondary that opens smoothly rather than all at once.
Getting it right has been a matter of hands-on tuning rather than following a single spec sheet — float level, idle mixture, accelerator pump timing, and secondary opening all interact, and the only way to actually dial it in is to drive it, listen to it, and adjust.
Notes for next time: an old, simple engine still rewards patience over guesswork. The Weber conversion is straightforward on paper, but the tuning pass after installing it is where the actual improvement comes from.
