Backlash was Distributor

[SuffolkD at aol.com]

I ask to this quote posted here and below Bernie:
"inasmuch as the driving cam gear is always doing so and the backlash is out 
of the loop.  Only if the cam drive system has a low frequency resonant 
torsional vibration................"

What about lift/close throttle after high RPM? 
Wouldn't the "driving cam gear" now backlash? as taken out of your example 
quoted above? 

My guess (from the education ya' all have provided me) is that this 
"backlash" during upshift or the like, could create the environment/situation for 
"cross fire " in a High HP/RPM 3B.

-Scott by BOSTON.... yes, I realize the Scott below is "QshipQ".  Just 
jumping in.
