[ercoupe-tech] Curiosity question

[Caliendo Dan]

Since my brakes have failed and I can't run up at usual rpm, I ran it  
up to about 1000 rpm and it was
very rough on one mag. Tried each mag during takeoff roll and again  
in flight and it is smooth at the
higher rpm's. Doesn't make sense to me as I would expect a weakness  
to show up at higher rpm's.
Anyone have an explanation....or should I start worrying about the  
health of my mags? (Fairly new
Slick mags.)
