From what I have read, that problem isn't really user serviceable. I have read posts of guys pressing them back in and even some guys using JB Weld to keep them in. Usually that is a problem that requires the engine to go back to YS.</div><div><br></div><div>Sorry to hear that!</div><div><br></div><div>Anthony<br><br>--- On <b>Tue, 6/2/09, Atwood, Mark <i><atwoodm@paragon-inc.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Atwood, Mark <atwoodm@paragon-inc.com><br>Subject: [NSRCA-discussion] YS Problem<br>To: "General pattern discussion" <nsrca-discussion@lists.nsrca.org><br>Date: Tuesday, June 2, 2009, 10:16 PM<br><br><div id="yiv1399352494">

<p class="MsoNormal">The short version… YS1.70DZ –
the brass fitting on the TOP of the head (towards the back) that has the black
check valve pressed onto it blew out of the engine in flight!! Needless
to say the motor quit.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">It appears to be a pressure fit. I pressed
it back in (I knew this wouldn’t work, but what the heck), started the
engine. It idled great, ran up great, took off, and as soon as the motor
warmed up (about two passes, pulled vertical and POP…dead as a
rock. Landed… and the fitting had popped out again.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">So I have a few questions…</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">What caused this to pop out in the first place??</p>
<p class="MsoNormal">What do I do to put it back in SECURELY</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">HELP!!!!</p>
