<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto">I’m late to this discussion. <div>I look for total advance when timing an engine. If I recall correctly my total advance is about 32 degrees BTDC at 3000 rpm. Set the initial mechanical timing and have distributor advance provide the rest. This usually involves changing the distributor springs to make the centrifugal advance quicker than factory specs. <div>J DiFede<br><br><div id="AppleMailSignature" dir="ltr">Sent from my iPhone</div><div dir="ltr"><br>On Apr 25, 2019, at 3:37 AM, PaulHunt73 via Mgs <<a href="mailto:mgs@autox.team.net">mgs@autox.team.net</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr">

<div><font size="2">Certainly the factory design overall is the compromise you
mention, and as said earlier the settings are chosen for a 'worst case' in
what can be quite a large variation between engines, plus a safety factor.
But given the components that come with any particular engine (of our
era) 'tuning' can only consist of setting the timing and the mixture, and
for those there is only one 'correct' setting. Get those right and you
will have the best performance and mileage, and by 'right' I mean right for your
engine and fuel. That may well mean more advance than book as I found,
which gave improved performance AND mileage, with no engine unreliability
over the 6 years and 60k I had it..</font></div>

<div>You also have to realize that factory specs are a compromise. They
are trying to balance performance, mileage engine life and in modern cars,
emissions. You can tune it for, let's say mileage, but performance
will suffer. Conversely, if you tune it for performance mileage will
suffer. Tune it the way you want it to
run.<br></div></blockquote>
