Wow, lots of very helpful info from everybody. I am extremely grateful for the advice and information. I've ordered a shop manual off ebay. Pulling the plugs today and take a peek inside and add the mystery oil (and putting the plugs back in so the rats don't poop in the cylinders).
My father modified the car a bit, converted to 12V and put an electric radiator fan on, and added an AC compressor for airconditioning. There seems to be an electric fuel pump below the tank, I'm assuming it's not stock as it's 12v.
I will assume the gas has all gone bad and will remove the tank and fuel lines to be cleaned/replaced, rebuild the carb, and clean or replace the fuel pumps, replace fuel filter.
Where do I get a carb rebuild kit that handles gasahol?
and what do I use to clean the gas varnish out of the tank and system?
I'm hoping I can determine if the rear main seal is rope or rubber lip from the service manual. Even if it's rubber I'm getting the impression I should keep a close eye on the oil seals after I get it running.
What all does 'going through the brake system' entail beyond draining and refilling and bleeding the lines?
Never done brake work before.
Thanks for the tips on wiring harnesses, currently it looks pretty good, just a few spots chewed down to the bare wire.
Will pull the oil pan and clean it all out.
Where do I get gaskets for that?
Again thank you very much all for the help, I feel much more confident about this project now!
