Hi everyone! I got "Immanuel" home last night! I found one spark plug wire that wasn't even on all the way. It improved it alot. Now she idles. It has new plugs and wires. A Distributor cap and rotor arrive Monday. My plan this week as follows:
#1. Pull Plugs Check Gap, take Photos.
#2. Install Distributor Cap & Rotor.
#3. Put her on a code reader.
I want to do this first befote compression check. Cause she has power. Its blowing a very little white exhaust which smells like fuel, like she's running "Rich". She smooths out quite a bit when I idle her up. I'm wondering if there might be a bad sensor or something? I'm going to post a video when I'm done with this post. I spent 3 hours hand washing her. She was extremely dirty from sitting under a tree for almost a year. Here's a list of new parts that was done by the previous owner.
#1. Master Cylinder
#2. New rear wheel cylinders
#3. Plugs and wires
#4. Fuel pump
Amazingly she is clean, clean, clean! no dents r scratches, and you can see she cleans up well. Solid Texas Truck it's whole life! It needs front seat covers. All the electrical works, all the lights, heat/ac and it has a Pyle Receiver that folds in and out and ROCKS! So I'm happy for $800.00 I will "Resurrect" this Esky. Definitely worth it. I just need to straighten out the rough running and ticking. Thanks guys. Video coming next.

You should change the distributor cap and rotor. I recommend Delco/Delphi or United DCR820X only.
It is a well known trouble spot on these.
If you dig around in your scanner, you can go to Live Data and watch the misfire counts per cylinder. Also short and long term Fuel Trims.

I bought the cap off Ebay. Not sure what brand to be honest. If there's a problem I'll definitely go Delco/Delphi. I'll be hooking a scanner soon. I dont have one yet. Thank you.

You said "little white exhaust" previously. So is it white exhaust smoke, black exhaust smoke or black soot at the tailpipe opening?
It's white exhaust, and it's warm where I'm at. Water is dripping from the exhaust as she's idling. If I Rev it, it throws a very little blue smoke. It has 225,000 on the clock. I'm praying since it was sitting for almost a year, it just has condensation in the system?

Sounds like condensation and the blue is likely valve seals.
I'm going to dump the oil this weekend and run some 10W30 Full Synthetic. After 500 miles I'll drop oil again. Freshen it up for the recommended mileage for brand between changes. Thank you as always and I'll probably pit some Lucas Oil Treatment in it too.
