The "soggy" throttle response may be due, in part, to retarded ignition timing.
1) Disconnect any/all vacuum lines at the distributor.
2) Set idle timing (as low an RPM as you can manage) at 10* BTDC.
3) At 3500 RPM check that timing is ~35* BTDC.
The water-heated aux air valve (AAV) is an ongoing source of trouble. They either stick closed, or more often, take 10-15 minutes at 80C water temp to close, if at all.
