Hi Doug,
I follow the never to old to learn philosophy.
That said, I learned so much from the D.V.D.s
offered from this company www.AutoShopVideos.com
The explanations are easy to understand ( even for me ) and it turned my Holly nightmare into, I can fix any Holly!
Anyone who wants to come out of the ditch on corroborators can do so with these D.V.D.s
The D.V.D. I ordered was "Performance Corroborators " it cured my ignorance,
I highly recommend them. I have now fixed and now they run perfectly four carbs!!! the old saying that you can't teach an old dog new tricks is B.S.
One of the issues I am having is with the data on the equivelent spark plugs.
Some one needs to explain to me how one "equivent" in another brand can be the replacement for a BF-22, BF-32, BF-42 all at the same time?
This is why I try to standardize the comparison using Champions as the standard.
If you tell me that it is because the "equivalent" plug has a greater heat range than the Champion does, my next comment would be that we are trying to limit the high temp of the plug to eliminate detonation by going to a colder plug.
How does a greater heat range limit the upper temperature range of the plug?
Help me here?
The plug I am using in the Pantera, an NGK BP6ES is one such creature.
It replaced the Champion N-8's which would foul up at idle.
I attributed this to the aluminum head running cooler and requiring a hotter plug.
If you look at the NGK chart, it is an equivalent to an N-8, N-9, N-10.
This is all too much for my puny brain to handle. Maas servesa por favor Senior. That's the only thing that will help I think?
One of the things I am suspecting, trying to research but can not confirm at the moment, is that the change in the "equivelent" listings is because there is a change in the nature of the fuels?
In the 60's we used lead fuel which had different burn characteristics then the current un'leaded/plus ethanol does?
Are the heat ranges specific to one fuel or the other?
Current pump unleaded burns hotter and cleaner. I suspect for that reason alone the fuel change COULD make dropping down to a colder plug necessary?
It just doesn't pay to think. It does little but create these massive migranes? I don't think, thinking is healthy for longevity.
What did Jackson Brown say? "I'm going to be a happy idiot and struggle for the legal tender?" Gee-se?
I will also bet you, "donuts to Navy credits", that these carbs are tuned for "stoio chemic" a/f at idle (14.6 and VERY HOT)? That would explain a lot.
