Yes, I've had the same sound under the same circumstances, except I don't
have a VP prop.
I think its the reduction drive dog clutch; the one that needs the periodic
friction test. I think its also possible that the surfaces of this may be
galled, hence the screeching. In my case I was rather hoping that it would
go away rather than having to investigate further (although the friction
check remains within tolerance and oil filter inspection didn't reveal an
abnormal amount of metal).
So far, it has gone away.
It might also be due (as the engine kicks backwards) to slippage in the
spragg clutch that engages (permanently) the starter motor to the engine;
but I doubt this, the noise seems to come from the front of the engine.
