<VV> 140 pinging update and results/ smelly car

[Pitts10ch at aol.com]

Ok Gents here it is:
 
I took the lower shrouds off of the Corsa today and went driving for a  
spell.  It turns out that it is hard to duplicate the pinging just by  myself with 
the shrouds off.  However, I checked the timing at idle once  she was warmed 
up.  It showed 8 degrees at idle.  As I throttled it up  it mechanically 
advanced up to a max of about the mid 20's.  Then with the  vacuum reinstalled it 
goes more than that......... into the unknown zone.   I have a rudimentary 
timing light so that's the best I can do right now.  I  went ahead and backed her 
down 2 degrees and the idle speed dropped a bit.   I test drove and found no 
problems except a lack of power when the hammers are  all the way down and the 
speed gets beyond 60 or so.  By the way, the  harmonic balancer is still 
intact.  I have a new Billet Clarks  version.  Anybody think changing is a good 
idea?  The highest temp I  saw on an 83 degree New England day was barely 300 
degrees on a long hill  climb.  And.....to all those Corsa stink mongers out 
there, taking the  lower shrouds off really cut back on the post drive stink.  I 
would guess  that the engine is quite a bit cooler and doesn't boil off as much 
fuel to cause  the stink.  No guarantees with that advice.  I will probably 
change  the Dbtr springs and check the accuracy of the vacuum advance in the 
near  future.  I'll let you know how it goes.  
 
Regards,
