Prop index or balance

Hi Don, Chuck told me to set the prop after the Mag click Chuck number is, 614-738-8604 think about an wonder how you are doing after the big blow how did the house far?

Should be 10 and 4 as you’re facing the front of the plane. There was a good article in the Capers a couple years ago about that. Maybe somebody out there remembers the issue.

Got the Alon back from its annual. The shop said they indexed the prop. When the engine stops I have prop blades at 11 and 5 o'clock. I now have a significant fibration anywhere below 2300 RPM. Does any one have the correct indexing information? The numbers are: C90-16-F with a McCauley 7150.
