<DIV><FONT face=Arial>If the crank is moving, it's bearings. Most likely the
rear. I'd replace both since it's going to be apart anyway. I'd be happy to help
you out with all this, but you'll need to get the bearings first.</FONT></DIV>

problem</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I just fired my YS-91 up after the valve
cleaning. It fired immediately and had plenty of power while still
running rich. After running for a minute or two the rpm's started
fluctuating a bit. The more it ran the less rpm's I was able to
maintain. I heard a noticable rattle that seemed to be coming from the
engine area. After the engine ran for about 5 minutes, the rpm's started
to drop more. I leaned the needle a little and the revs didn't increase,
so I richened it back up and idled down, the motor died. I felt the
spinner to see if it was warm and it wasn't, that's when I noticed the
movement of the output shaft. My first thought is the front bearing, I
have quite a bit of movement up and down and a little side to
side.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I guess I'm not meant to fly this plane.
Does anybody know where I can get a good YS-91, cheap?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think this one is going back to
YS.</FONT></DIV>
