Please help I’m Stuck It’s been 5 months

I would pul th gas tank, get rid of what could be old stinky gas an rust and dirt, clean it out good, make sure the pickup is not 40 years old, or clogged up, new repop off Fee bay is cheap Mae sure it has the ground strap. There at=re many threads on here about getting yor fuel filter to work. Hit search.
I would go to Amazon and look for a book called "auto mechanic fundamntals" by Stockel. It will tell you a lot of what you need to know, Good read for any young guy.
If this slant has points, get a set and a condenser, if not needed now keep for spare. Check it cap and rotor for obvious wear. If it has solid lifters, learn to set valve lash.
Just remember don't get overwhelmed, it takes time for anyone to get familiar with it all.
