This is a what I'm Working On Now post.
I welded the O2 bung in and wired up the wideband AFR gauge, and it says the car is running dead rich/offscale for the first couple of minutes until it warms up and the choke opens, at which point it flips right up to dead lean/offscale.
The car runs and idles okay. I'm working on looking for vacuum leaks, which are pretty likely. (It's an A14 not in a Datsun, so it doesn't have an air intake, just a big filter, and stuff like the hardware to pull the intake air across the exhaust until the engine warms up is plugged, but is it plugged well enough?)
When I did the transplant I built a sort of analog computer to simulate some of the inputs to carb sensors that don't exist in this car.
But this is definitely convincing me I need to just chuck the Hitachi and head for fuel injection.
