Tach running backwards
      
      
      Team,
      
      I've got about 600 hours on my Yak 52 so, like most of you, I've had  
      wacky readings on the RPM gauge before and found a broken wire in the  
      cannon plug at the tach sensor. Nothing new here. Except this time I  
      repaired the broken wire and the gauge now runs backwards. I've never  
      seen that before, but I know others say it is characteristic of a  
      broken wire as well, so I pulled the plug off again and did a  
      continuity check to the rear RPM gauge. Everything checks out. Good  
      continuity, no dry solder joints, but the RPM gauge continues to run  
      backwards. Anybody got an idea what I'm missing?
      
      Dave.

      This is my first post in this forum and want to thank Matt for maintaining it.
      
      
      I have an M14P that I'm in the process of de-preserving.  The motor's currently
      hanging from a hoist with its motor mount attached.  As I'm draining the oil
      from various places, I found some paraffin in the cylinders.  
      
      What I'd like to do is flush the motor and cylinders out with something.  At this
      point I'm not sure what to use.  I feel the safest thing would be to use some
      Aeroshell W120 oil diluted with 100LL.  I don't know what chemicals would adversely
      affect the seals in the motor.  Looking for recommendations.    
      
      I have read through all the task cards in the maintenance manual but haven't found
      anything regarding a break-in procedure.  Does one exist?
      
      Thanks in advance for any advice
