<HTML><BODY BGCOLOR="#ffffff" STYLE="font:10pt verdana; border:none;background-color:#ffffff; "><DIV>Bill</DIV> <DIV>I rebuilt my eng (webra 145) after 80 flights because pump problems made it run lean(Sag). After the rebuild, piston, ring and rod it was throwing black exhaust. The type black exhaust that ruins clothes if you get it on you. Now after 35 flights the black is turning to a exhaust colored brown. I'm sure this is the ring wearing in with the sleeve. Hopefully this is your case.</DIV> <DIV> </DIV> <DIV>Jim Ivey </DIV> <DIV> </DIV> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt Arial">----- Original Message -----</DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt Arial; COLOR: black"><B>From:</B> Bill Pritchett</DIV> <DIV style="FONT: 10pt Arial"><B>Sent:</B> Friday, July 25, 2003 5:38 PM</DIV> <DIV style="FONT: 10pt Arial"><B>To:</B> discussion@nsrca.org</DIV> <DIV style="FONT: 10pt Arial"><B>Subject:</B> Webra 1.45</DIV> <DIV> </DIV> <META content="MSHTML 6.00.2800.1170" name=GENERATOR> <STYLE></STYLE> <DIV><FONT face=Arial size=2>I've just completed test flying my new Focus, and the plane is great.
