Default Question from a friend

When doing a mag check (C-172, O-320) what causes an rpm increase. Yes, increase not decrease.
Thanks for the answers, Mike

I'd guess one of the mags is timed way ahead of the optimal time. Once it is fired first, the second one does not add much, but once the it is turned off, the second one fires at optimal angle, thus RPM increase.

Just a guess.
