<VV> Setting the Timing

[BobHelt at aol.com]

Hi Stephen,
If the end of the little aluminum tag on the timing scale doesn't go to 24  
degrees, then you don't have the type of 110 hp engine that allows timing 
to be  set to 24 deg. See the 1965 Shop Manual, page 6-60 for a photo.
 
14 degrees is a good setting to start with. You might have to set it back a 
 degree or so later.
 
If you have never actually heard detonation, then have a club member  
demonstrate it for you. Bring it up for discussion at a club meeting. I am truly  
surprised  that you do not know this sound, especially considering how  
prone Corvairs are to detonation. You MUST get your ears trained for this 
sound.  It is necessary so that you can use it as a sense of impending doom to 
the  engine if loud (bad) enough.
Regards,
Bob Helt

This  is just another reason to love Texas!  I thought it was pretty   
clear, but let me use the correct terminology; the timing scale goes   
to 16 degrees advance (18 if you count the end of the aluminum scale  -  
no number here; just an educated guess).
The next question is :  How does one know that detonation is  
occurring?  I  that  believe it is a sound (pinging ?), but I have  
never experienced  it.  This is just another reason to love Texas.  Is  
the  pinging like the old submarine movies only speeded up?  The   
members of NTCA and I have spent considerable time and effort (and   
money on my part) rebuilding this engine, and the last thing that I   
need to do is something that would jeopardize that. I really need to   
know what I'm looking for (detonation).
