<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a YS-91AC that came in a plane I aquired
last weekend. On the 16th flight I lost the motor about 2 minutes into my
routine. After a safe, and pretty nice landing, I might add, I brought it
back to the pits to see what happened. I could turn the prop by hand with
almost no back-pressure. </FONT></DIV>
<DIV><FONT face=Arial size=2>I pulled the motor out when I got home and checked
it out the best I know how. Pulling off the backplate I see the connecting
rod and piston seem to be OK and the valves seem to be moving like they're
supposed to. I don't know a lot about these engines, as this is the first
YS I've run in a plane. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What I need to know is where is the best place to
send the motor to be checked out and re-built. I don't want it just
patched up, I would like it done right, but a quick turn around.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Asking too much?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance,</FONT></DIV>
