Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, what is the burn color of the spark plug tip?

Still and strictly based on "...New...vacuum hose...will not idle...", then it could possibly be a vacuum leak (most likely) and/or a too rich mix (least likely). Re-check the new vacuum hose, fitting and connection points.
