Mixture too rich?

I can't see an annual inspection not doing a complete runup including mags/mixture/etc.  Gladys just came out of this years annual.  At Clarences shop a pre and post annual runup is done.  It's also included in the Mooney Annual/100 hour inspection guide: http://67m20e.com/Mooney 100 Hour Annual.pdf

 

You're right, it's right there in the post-inspection checklist

I really think you should ask your mechanic to do engine operational checks before they even start opening up for the inspection, identify any issues (ie mixture cut off) that can be repaired, adjusted, before the aircraft is depaneled, or looked into during the inspection. Then again at the completion of the inspection.
