<DIV><FONT face=Arial size=2>Bob,</FONT></DIV>
<DIV><FONT face=Arial size=2> How much time is on it? We've had a few
around here that ate the rear bearing in 50 - 100 flights. One of them ended up
ruining the sleeve too (bearing debris). The solution is to replace the rear
bearing with an OS 140Rx F.I. (sealed) bearing before it gets bad enough to
cause other damage. The front bearing is a double sealed type already so you
won't need to change that one. This is a really good running motor when you get
the bearing thing straightened out.</FONT></DIV>

AX</DIV>
<DIV><BR></DIV>
<DIV>I acquired a plane with an OS 120AX installed, and seem to be having some
issues with it. It came with an APC 16x8 prop and stock muffler. Is not
running as well as I think it should, but I did figure out I had some bad
fuel. I plan to go out again today and tinker with it some more.</DIV>
<DIV> </DIV>
<DIV>What fuel, prop, and what rpm figures should I be seeing?</DIV>
<DIV> </DIV>
<DIV>Thanks in advance.</DIV>
