So we got the pump and the flow divider back. I put about 5 hrs on it, climb to 15K few flights around, all was good. Then today i had problems again, here is the chain of events:
Sump all the tanks, no water
Started the plane all good
Run up all good
Took of to 12,500 towards modesto -> all good
Got to 12,500 feet all good
after leveling:
Reduced power to 30 MP, RPM to 2400
During the leaning procedure after hitting 11 GPH it suddenly dropped
Turned on the boost pump (low) engine came back
Turned around towards watsonville and initiated a slow decent (i was just passed the hills at hollister)
I then turned off the boost pump, flew for a bit and the problem cameback
from the graphs you can see i had 5 fuel flow loss
the boost pump (low) always made it came back sometime for a few minutes on the 4th for about 30m
the orange line is the fuel flow
We fixed the tanks, rebuilt the fuel pump and flow divider. Rebuilt the fuel selector and gascolator. Rebuilt the mags and re place all the sparkplugs.
Top end is new, bottom is from 2016 with 800 hrs.
Any idea what could cause this?
Note: the EGT probe on 5 needs to be replaced (Green) hence is all over the place
Thank you
