Assuming the details of the incident as presented are correct, then two facts stand out.
1) The instructor allowed the engine to be grossly overprimed
2) The POH procedure for an engine fire at start up was not followed
Fact 1 speaks to a poor appreciation of good practices in the operation of a pretty simple piston engine which is pretty sad, but fact 2 speaks to a
wholly unacceptable lack of skill and knowledge by the instructor.
