Aside from the fact that the valve cover on Healeys is not flat I question what a smooth idle has to do with WOT or high-end performance, but it does sound charming. Another is to retard until pinging occurs but I have heard and read that there is something called "silent pinging".</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff">When I set timing on my 100 I do it at high rpm's (2500 to 3000) with a light and look for 34-35 degrees of advance. Anything beyond that causes my engine to overheat and sometimes I will take a degree or two off that if engine temps suggest.</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff">Best--Michael Oritt</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff"> </div><div class="gmail_default" style="color:#3333ff">I have heard (not seen) people </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, May 26, 2021 at 5:16 PM John Vrugtman via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

way I used to do that was advance timing and test drive lugging in
high gear, when pinging started, it was time to retard slightly to
avoid pinging. Worked fine.<br>

Please do not reply to me and tell me what the factory spec is
or what the total advance should be or anything else you assume
I don't know. I simply have a keen interest in knowing about
"old school" techniques and how to apply them. <br>

<div>There was a discussion at the Conclave tech session
about ignition timing..... advancing the distributor to a
certain point and then backing off a certain amount.....
without using a timing light. I cannot remember the
specific details but I would like to try it. Does anyone
have the exact details of the procedure?</div>
