73 valiant runs good then randomly dies

If it came to my shop, i would be all over it.
But any other local shop i know of would be lost.
The industry has raised nothing but a bunch of parts changers.
I grew up fixing parts,as they were intended when manufactured.
Not one shop i know of will rebuild a carb. Will pull it and send it off,same with transmissions.
But i grew up broke, needed to figure this stuff out.
