It is supposed to run like crap with Temp II disconnected.

Use your timing light. With the engine running at idle set the timing so
the mark on the pulley lines up with the case split.  That is close
enough to run ok unless something else is wrong.

When did the tach stop working? The tach signal comes from the ignition
coil, on the smaller of the 2 green wires that plug into the coil.
