<VV> Fwd: valve noise

[Mikeamauro at aol.com]

"...Thanks for all the help. It is proof positive that the previous  negative 
message regarding Corvair owners is incorrect.
The  noise is gone,but the performance is less. I retarded the timing to 12 
degrees.  This solved the noise,but the car would stall out at idle,so then 
increased the  idle speed. Better but still sluggish,so "fiddled" with mixture. 
Some  improvement. Then tried various point gaps. Ran best at .0012. Still not 
where  it was. Any ideas?
Thanks.      Rookie Corvair  Owner      Pete ..."
 
Best Fix: reduce the head quench space to .032 (see Corvair technical  
guide). Had similar problems with my 67, 110, factory A/C, powerglide; reworked  
heads to reduce the quench and problems are history. Also using a Safeguard  
electronic knock sensing device to automatically and selectively retard the  
timing (See: _http://www.american-pi.com/safeguard/safeguard2.html_ 
(http://www.american-pi.com/safeguard/safeguard2.html)  ).  I run 18-degrees initial advance 
with stock distributor curve and # 52  jets; presently, with the ambient temp 
in the upper 80s to 90, with A/C on  full, get just an occasional, slight ping 
(which the Safeguard sees; light  up one knock indicator LED before the knock 
is clipped). Zip is good, and on a  recent trip averaged 23 MPG with speeds @ 
70 and higher. Presently experimenting  with leaning out the mid-range to 
improve the mileage further.
