Start with the basics.
REplace the cap,rotor,leads and plugs. Set the timing correctly.
Check the engines compression.
Do the valves (if it has the adjustable tappets)
Check the throttle linkage to make sure you are getting full throttle and no play exists in the linkage .All parts are available and after 200,000 the linkage Will be sloppy.
Replace the manifold O rings.
With the manifold apart you will need to get the injectors cleaned ( there are plenty of places that do it for a cost per injector).
i would also consider replacing the fuel distributor at that milage too. Again there are places that do an exchange service on these.
Once you have that organized,consider changing the cold start injector.
This is probably what is causing the excess fuel as it may be stuck open.
This is all very basic stuff .
The complex stuff begins now.
At that milage the timing chain and tensioner need replacing.
If the car has been running rich there is every chance that the bores are getting worn so the compression may be down a bit.
Check the thermostat and see if it is closing properly. A cold running engine will run rich continually.
Although the Kjet cars aren't as powerful as the djet injected 450's it should still be a spirited performer on the road.
