How much can one compensate for the other?
For example, with larger jets and idle screws further in, could you tune a set of carbs identically to another set of the same carbs that had smaller jets with the mix screw further out? I want to experiment with going a little leaner at idle and seeing how my engine likes it. I'm trying to decide if I should order a smaller set of idle jets or if I can achieve the same result by just turning the screws in further. Basically, what is the difference? Don't they achieve the same ends? Obviously there's a limit on the rich side because there's only so much fuel a jet will allow to flow. But if you're trying to lean it out, what's the difference between going to a smaller jet or just turning in the screw? |

Haha, yeah you're probably right. And if this were any of the ACVW's I've previously owned, I probably wouldn't even be bothered and, like you said, just chalk it up to it being a 40 year old car.
But this car, with the 4 channel digital CHT gauge and the digital AFR gauge, I've got so much more information coming at me constantly that I'd otherwise be oblivious to in any other car. Gives me a case of the "want-to-tweaks" and iron out every little wrinkle (IMG:style_emoticons/default/biggrin.gif) |
