I have had over 80 flights on my ProLine now with the exact set up, and it's still spotless clean after every flight. Becareful on the angle between the header and the pipe, the contact point between the header and the engine, and the gap where the header and the pipe connect. I also changed all of the gaskets and the o-rings after every 60 to 70 flights, and that tends to cure the problem.<br><br><br><blockquote style="border-left: 2px solid rgb(0, 0, 255); padding-left: 5px; margin-left: 0px;">-----Original Message-----

Guys,<o:p></o:p></span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">What is the final verdict on these
O-rings? Will a warm run melt the O-ring? Does the viton
replacement fit tight enough over the header? Recently my plane is
getting really messy, where as before there wasnt a drop of burnt fuel ahead
of the exhaust stinger. I replaced the o-ring but still had the
mess. I pull the motor last night and checked out everything and the
motor looks great, bolts were tight, with no indication of any leakage from
the motor or header to motor/flange attachment.

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I am using the Nishioka spring
clamp mount. All things considered and experienced, I think I prefer the
stock Hatori mount that comes with the pipe. The Nishioka seems to allow
for more fore and aft pipe slippage during running due to the thin vertical
white plastic supports (checked while running the plane upside down to try and
determine spray pattern and such - in which I didnt find one, which
leads me to believe that it starts to happen maybe later in the flight or heat
cycle, versus the small amount of running I did as a cursory
check.<o:p></o:p></span></font></p>
