Hi Harith,

What engine is this on, a 912UL or ULS?

How much of a mag drop and at what rpm? You also shouldn't be doing a mag drop on either one at 1700 rpm and it would be especially shaky at that low rpm. Do a mag drop between 3500-4000 rpm and let us know. Depending on the type of tach read out you have (electronic verses analog) it should be around 60-100 rpm which would be more in the normal range.
