I know this has been asked numerous times, but I just do not seem to get it. So, here it goes again. Sorry...
Again, the engine is a 502 with an 8-71, I am fouling plugs rather quickly. The spark plugs in it now are AC Delco Rapidfire #4's. Carbs are set good. Every where I read, and have been told here, set the initial timing 16 to 18 degrees.
At first, I set the timing to 12, runs great and very strong, but fouled the plugs. Car was not driven much at all, but still the plugs were extremely black.
I changed the plugs out, with the same as above. I went ahead and attempted 16 degrees, but the black smoke and raw fuel was extremely bad. I stopped there.
I have a question about going two steps colder on the spark plugs, I ask and ask, but it does not make sense as to why. How is going with a colder plug going to help this? It would make since going to a hotter plug.
Do you think that a colder plug and keeping the timing at, lets say 12 to 14, would be better? Borti stated he went 1 step hotter, and it would better for the street.
Now, I did call the blower shop - they said two steps colder, went to a race shop where I get my fuel - they said the same, called NGK tech support - they too said colder plugs.
Give me some advice please. It is irritating me...
Thank You,
Jason
