<VV> 140 pinging test drive

[Pitts10ch at aol.com]

OK,
Here it is.....  As you all know, I had pinging problems.  I took  off the 
shrouds and set timing to 6 at idle.  At first I thought this was  ok.  It 
isn't.  I always learn the hard way.  The result of this  turned out to be my 
hesitation problem.  I reset timing to 16 at idle and  now I am back to occasional 
pinging.  I have been experimenting (when time  permits) with this setting.  I 
am now at 14 and without a vacuum advance  connected.  This seems pretty 
good.  I plan to clean the engine out  next.  I think that with new springs in the 
distributor and a calibrated  vacuum advance, we should be golden.  I am 
seeing 300 degree cylinder head  temps.  As for the standard Corsa Stink.  It came 
back with the higher  timing numbers.  Severely retarding must cause less 
unburned fuel to steam  out of the carbs after shut down.  I basically drive too 
fast on curvy back  roads and about 75 on the highway.  Does anyone have temps 
far different  than 300 under the same conditions?  Thanks.
