Larry, I'd say the rotor disc pin was loose. They probably pushed it back
and retightened the grub screw. Now your rotor disc and back plate clearance
is OK it will run again.

In the worst case scenario, which actually happened to me ..the pin moved
forward and into the path of the con rod. Things got very ugly at that point
as you can imagine.

You , by the sound of it, were lucky. 

Enjoy the engine, they are good.....but the 160, well, they are just sweet!!

I sent an engine into YS Performance and on the paper I received today it
stated they "adjusted the back plate".They did take care of me so this is
-not- a complaint. I will probably call YS to ask about it, but has any body
else had this problem? Is it something that the average pilot learns about
with YS engines?

I'm not the best engine guy around to begin with and the YS DZ is new to me.


It ran great for practice flights and up through the 3rd round. On the 4th
round it died in a stall turn. I got it started and then it quickly died at
idle and would not restart. I sent it in to YS Performance and they took
care of it.

YS got the engine running and it was in warranty, but curious about the back
plate adjustment comment.
