Since you still have the tamper-proof plug you should not be very far off on the mixture adjustment. You either have dirty fuel injectors or misfiring spark plugs. You should see a nice pattern from the injectors, not a stream or a dribble. If you don't know how old the wires are replace them, the cap and rotor. A new set of plugs would also be good. If it is still very rich on start-up the cold start system may not be working correctly. Make sure that there is nothing plugged into the Hot Start Plug by the fuse block. Make sure that the air filter is not dirty and the air sensor plate does not rub on the sides of the venturi.
