<DIV><SPAN class=820532403-04092006>Nice. Well, the bearings in my OS 160 are
still fine... Sorry guys. You knew someone had to do that. Seriously, how does
the pin go into the piston? Is it held with clips? I wonder if the fit is too
tight. Full floating pins (pins that ARE held with clips) should be fairly loose
in the piston and the rod. Maybe it's just a fit problem and not a weakness. If
anybody has a new motor it might be worth taking it apart to see if the pin fit
is really tight.</SPAN></DIV>

<DIV><FONT face=Arial>Just wondering if anyone else has experienced a
problem with the piston cracking arounf the wrist pin boss. I now
have a second one with this same problem. It like the first one
was running like gangbusters and gradually started losing power. On tear
down the cracked piston was very evident. Going to send this one baxck
to YS with the first piston also. Looks like the larger piston in the
160 is weak in the center.</FONT></DIV>
