<VV> Single Carburetor - Better formatted

[Sethracer at aol.com]

I wasn't ignoring you Mike, honest. If that one works for you, that's  
great. I asked the guy which distributor he was using and I haven't heard back  
as yet. Reference your note, GM was using ported vacuum way before  
emissions were much of an issue. I agree that the mechanical advance eventually  
(~68) got really goofy with tiny initial advance (some Corvairs were at 4  
degrees, as I recall.) But if he starts at 12 degrees (initial only) - the  
early 110HP standard setting -(depending on which distributor he is  using) a 
full manifold idle vacuum will give him a bunch of advance at  idle. Advance 
that will evaporate when the throttle is opened. It would be even  worse if 
he has set the initial advance with the vacuum connected. That's why I  asked 
about the distributor. I do agree on the heat under the carb. Have you  
seen people route the "recirculation" air off the exhaust manifolds (which is  
also formerly cooling air) up to the carb, like the V8s do, with a vacuum  
door and a hose feed? That should help in heating the input air. -  Seth

I sent  it to Seth off-line, and he won’t answer me....I’m only relating 
to you what  works really well in my hands....isn’t that what his forum is 
supposed to be  about...? the sharing of experiences and ideas....?
You can theorize all  day long, but it still doesn’t refute what actually 
works....and I do LOTS of  these....?
