Reusing stretched timing set....?

3/4 slack though not optimum isn't enough to matter in an inexpensive just make it ok driver, and it sure isn't enough to warrant advancing it.
I say throw it in stock and run it, or advance it just for the fun of it if you want.

Oh yea, just my opinion. :D

That brings up the question, about how many degrees of timing retard would that much slack equal? My timing set only does +/- 4 degrees or zero, nothing in between...
