A mechanic friend recently suggested the following method for setting timing
on an older engine such as the A-series:
1. Let the gas tank get near empty, then add a gallon or so of an economy
grade fuel.
2. Set the timing as far advanced as it will go until it starts pinging
while under load.
3. Then fill the tank up with premium fuel.
He claims that with a high octane fuel, it won't ping as early, and thus
should provide peppy performance.
I regarded this with skepticism, of course, but this fellow has been a
mechanic for many years, and has set up more than a few racing engines. Is
this a reasonable method? Or will I still be "detonating" the mixture?
