Questions regarding performance
      
      
      Is the prop a two blade or a three blade?

      I have a Europa XS with Whirl Wind ground adjustable prop. It's taken me
      three years to get this engine up to speed.  I flew from KDWA to KCGZ
      (Copper State Fly-in). Then back on Sunday.  I averaged 6.0 Gph, 110 kts. My
      IAS 96-98kts TAS 105 at 2950 rpm my manifold gauge shows about 16-18 inches.
      Takeoff RPM's about 2850@85kts. It will over speed in cruise if I let it.
      
      At one time it seemed that I could get 115 kts IAS, but now it only in the
      90's.  
      Just started my first hundred hour inspection. Compression were low of 66/80
      high of 74/80.
      
      I have the HACman installed and use it for climb out as the engine runs
      rough if I don't lean.  I have a 245 main jet installed. Cruise numbers are
      good and almost even at 640-680 @2950
      
      I was wondering if anybody has a Lighten on this brog?
      
      If it what your thoughts on what I have written!
