<DIV></DIV>Sure I just get upstairs after pulling the motor apart again and
swapping out the cylinder liner for one from another motor. Looked almost
new no burn marks but my son is getting frustrated with little flying time each
time at the field so I changed it just in case. Put both motors back
together reinstalled the motor in the plane. Found a new muffler in the
box, put that on. Only to find that I should have changed the front
bearing as well :)<BR>Can you be a little quicker next time Ron? :)<BR>If
this doesn't work next time the bearing and anything else suggested.
Bearings feel fine though. Engine was really almost new. Not even
much carbon or varnish at the valves.<BR>Thanks,<BR>Stu<BR><BR><A

<DIV>I've had the same problem before. It was the front bearing. The bearing
heats up the front of the motor, then the regulator, vaporizing the fuel.
Better known as vapor lock.</DIV>

<DIV>Try a different pipe. I know a flyer who had this same problem some
years ago, not with an AC though. He tried everything and the problem kept
hounding him. Turned out that the pipe was plugging up when it heated up
and restricting the exhuast flow. </DIV>
