Even better than "Over the Top"
If you can see only one arm-wrestling film, make it this one. If you can see two, see this and "Over the Top" on a double bill. Or not. It's your life.
I found it curious that P.K. is the kid and Kid is the adult, but that quirkiness is one of many factors that make this an appealing little forgotten gem. It's a very entertaining road movie with plenty of oddball characters and a predictable but sweet plot. 7/10 stars from me.
