<DIV>Lance,</DIV>
<DIV> </DIV>
<DIV>Now you said that, I think I have that problem with an OS 160 that I
replaced the bearings not long ago. The engine never wanted to run like
the others and as before after replacing the bearing. I bet that I
didn't align the ring with the pin. </DIV>
<DIV> </DIV>
<DIV>Thanks for the "eye opener"</DIV>
