My thought is if he plugs this unused retard port, the internal diaphragm may not move appropriately to the advance side because of a sealed vacuum condition on the retard side.<o:p></o:p></span></pre><p class=MsoNormal>Dave Pallo<o:p></o:p></p><p class=MsoNormal>’72 Square ~ Elwood<o:p></o:p></p><p class=MsoNormal>Fairport, New York<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><pre><span style='font-family:"Courier New"'><o:p> </o:p></span></pre></div></body></html>
