Paul – boy, I hope not. I already
have the lightweight Skytec starter, which is supposed to be friendly to the starter
adapter. The starter adapter was replaced at 50 hours by the previous owner of
this engine (it now has around 275hrs). I’ll keep an eye on the situation
to see if gets worse.
I’m not aware of any options or
choices to be made regarding the starter adapter. You simply have it rebuilt or
replaced. Is that correct?
Thanks,

down hydraulic pressure
Adam, great video. I hate to add this comment but I believe you
have an old geared starter, perhaps an iskra or other geared starter?
Maybe batteries were not charged too. But, the starter is spinning
and the prop is going backwards for a short duration during start in your
video. In my non-expert opinion you are a candidate for a new starter
adapter. That spinning is the spring slipping on the adapter shaft.
It will get worse with time. If it's under warranty consider
getting it swapped and putting in a better starter. I have great starts
with the old tcm boat anchor and another legacy now has the newer skytek with a
rebuilt starter adapter and that is working well. I'll send you a video
of how it looks after the change. Let me know if you need more data.

The attached
JPG file shows the up and down hydraulic pressure readings throughout the
flight. The x-axis is time, with the flight beginning at 20:32Z and ending at
21:12Z. You can see the gear retraction tests beginning around 20:43 and 3500'
altitude. Notice that after the last test the down pressure remains around
500psi for about 90 seconds even though the gear is retracted. The up pressure
fluctuates a bit then the down pressure drops to near
