 A brief history of my IO-550n which was built by Performance.  After 240
hours the crank gear which actuates spinning the crankshaft from the starter
sheared. There are 6 bolts and a spline which must fail for this to happen.
The prevailing theory is over torquing of the bolts. Lucky this was not an
inflight catastrophic failure and after having the engine rebuilt at Barrett
Precision Engines I am in the process of putting the engine back on the plane.
 My fuel pump was rebuilt and I am having trouble rerouting the hoses to the
fuel pump without interfering with the mixture control.  My pictures before
disassembly have not been helpful.  Specifically the large fuel line from the
gascolator to the elbow fitting on the left side of the fuel pump runs into
the mixture control. This was never an issue in the original assembly and I
was wondering if someone had a picture or some insight into what might have
changed.  I an not sure if the rebuilt fuel pump is exactly the same as the
original and I am tracking this down as well.
