I sold a Chevy S-10 4.3 to a neighbor just over two years ago,,, $1,000,,,
JUST this past Saturday,, he complained to me that a coolant carrying metal tube that is next to the intake manifold was leaking,,
and he was complaining like I should do something to help him get it fixed,,,,
So, this goes both ways,,,
I say buyer (or seller) beware, if you are expecting perfection,, go to Home Depot, not the forum, or Craigs List,,,
P.S. If the OP paid $4,500 or more for a 1968 Cub Cadet, and it was not correct,, tell us about it here.
If the OP paid under $1,000 expect there to be issues.
In between,, I do not have an answer,,,,
