What I meant by this is that no matter how lean the air fuel mixture is the exhaust is still full of raw fuel. I tracked down (I think) most of the problem(s). I pulled the air intake today to check that the plug wires weren't swapped around and found that the dist. cap wasn't seated properly and that I had gotten the fuel lines from the cpr and the cold start valve switched around. STUPID, STUPID STUPID. I don't know how many times Ive disconnected those and put them back over the years. I looked at the fuel lines, compared them to the diagram and still missed it. I realized that although I had cleaned and re-gapped the plugs last weekend they were fouled with soot from cylinders not firing because of A) the dist cap sitting cockeyed so it wasn't firing on all cylinders and B) Fuel all out of whack from having the lines hooked up wrong . So I think that this was a combination of Dead RPM relay Fouled 02 sensor Dead Frequency valve Dist cap not seated My stupidity in switching the lines around Sooted plugs Plugs not gapped correctly , bad plug wires, carbon tracked cap and weak coil (when I started into this whole mess) I changed out a plug that was fouled and wasn't firing and things ran a lot better. Will change out the rest of the plugs tomorrow and I am keeping my fingers crossed that I will have a running vehicle again. >> The above was written on Saturday so now for the update. Changed out the sooted plugs and fired things up. BINGO! Got the mixture dialed in and thing were great. Hopped into the car to try it out and at the end of the street it lost power and died. Started it up again and headed home with the car surging badly. I thought to myself "now why is that fuel pump so noisy" . To add insult to injury, with all this idling too rich in the driveway I had ran the car out of gas and the fuel sender decided to not read correctly. I put in the gallon of gas for the mower and headed down the street to the gas station where it took 13.5 gallons to fill up. I drove it around for the next half hour to clean the soot off the 02 sensor and out of the exhaust system. More that I drove it the better it ran. The car idles without a miss and holds rock steady at about 775 rpms. Took it home parked it, washed it and then changed the wiper seal and "cat whisker seal " for the toll booth window. Apparently the poor old window motor couldn't handle the new seals and the cable popped out of the guide tube when I rolled up the window so I know what my next project will be LOL. While I have the door open I will be changing the door lock to make it a one key system then all my adventures inside the door will be done and I can put the plastic sheet on, put the door panels back on for the last time and forget about digging around inside it for a good long time.
