1995 Toyota Camry almost full rich fuel feed

I PERFORMED A VALVE JOB AFTER AN OVERHEAT CAUSED A HEAD GASKET LEAK. EVERYTHING WENT WELL, CAMS LINEUP, ALL IS WELL EXCEPT RICH FUEL SUPPLY ON START AND AFTER WARMED-UP. SO RICH IT WILL BARLY IDLE AND OF COURS FOULS PLUGS. WILL RUN AT HIGH SPEED BUT NOT LOWER SPEEDS. ALL GROUNDS ARE GOOD, THE READOUT IS 52 KNOCK SENSOR. HOWEVER 4 CYLS. DON'T HAVE KNOCK SENSOR. NO OTHER CODES PRESENT EXCEPT OBVIOUS OVER FUELING RELATED EMISSION WARNINGS. OBD-1 SYSTEM. SPARK IS STRONG, COMPRESSION IS GOOD, FUEL IS FRESH TPS IS WITHIN LIMITS, O2 SENSORS OK JUST DIRTY FROM EXCESS FUEL. CAN'T FIGURE IT OUT.
