replace the check valve. </FONT></DIV>

they've run well in the past and start acting up, many times it's just a
tiny piece of crap driving you nuts.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi Jerry,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>You might check to see if your motor mount
or something else has loosened a bit and allows some part to
come in contact with something it shouldn't--like pinching a line.
Possibly look at the nose ring area and a shift that may cause some
drag. Don't you love the intermittent mystery?!</FONT></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>Any help would be
appreciated.</FONT></DIV>
