<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff>I have a YS 120ac that
has been a strong runner in the past. Would turn a 15x12 apc 8300-8400 on 25%
powermaster. It was rebuilt last season but never run till this season. It was
giving me fits at Hamburg contest and taching is only showing 7800 to 8000.
Needle 1 1/4 out. Seems to spit more fuel out of air inlet than I used to see.

<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff>My question being am I
being unrealistic expecting it to continue to give me 8300-8400 on that prop
& fuel. Valves check at 002 piston TDC cold. Good seal in valves. Don't
feel any drag from bearings but I replaced bearings last time and was
surprised on ratty they were after dis-assembly. Might my bearings be the
culprit and next item to explore?</FONT></STRONG></DIV>
