[Mgs] Timing discussion

[Charley Robinson]

That comment,  "Just advance the timing until you notice preignition."  
has to be taken in the context of how much advance can you dial in 
before it starts to ping under load.   It's a rough attempt to dial in a 
particular engine/fuel combination.  I think most of us know the trial 
and error method.

To answer your question: My B engine is set at ~12* advance @ 850 - 900 
RPM with the vac disconnected.  It pulls well through the midrange  set 
that way.  But my engine kind of "parts is parts." It's a 18V block with 
GH innards (flat -top pistons).  All this topped by a pre-smog head and 
HS-4 carbs.  So I had to tweak it to get it to run the way I like it on 
mid-grade gas.
