<DIV><SPAN class=873375620-20052005><FONT face=Arial color=#0000ff size=2>Last
weekend, after 2 seemingly perfect runs, we experienced the same problem with a
140sport. The engine was dying on exit from the triangle loop. It
was my son's first contest so we obviously panicked. Changed plugs,
checked lines, checked tank and clunk. Idled and ran great on the
ground. Turns out we were rich on the high end and as the afternoon got
warmer and more humid the engine was loading up on the
downlines.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Anyone have any ideas why this engine quits
running when exiting the triangle loop or the full roll after the half
inside loop in the Masters pattern.</FONT></DIV>
<DIV><FONT face=Arial size=2>I can't remember ever having this engine quit
since it was new. I've checked the fuel lines, replaced the pickup line in the
tank, changed the diaphragm, checked the fuel passages in the regulator and
carb, changed plugs, reset the idle screw and cleaned the filter. It runs
fine with plenty of power (for an AC) and it doesn't quit on the above
maneuvers every time.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help would be appreciated.</FONT></DIV>
