That exact thing happened to my tenant on his 85.

Took him an hour and a half to get 5 miles home after he picked it up as
the shop was closing for the day. Drive 100 yds, let the smoke stop,
drive another 100, etc...

I checked out everything for him.

It was a bad master cylinder rebuild. You need to take it back.
