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? |

Ok,
Sounds like a great car that runs perfectly fine. What are you bitching about? Just drive it.... (IMG:style_emoticons/default/smile.gif) I realized today that my 911 was not nearly as smooth as my big Audi. Oh, my 911 is over 30 years old and the Audi is less than ten.... My 914 was never without hiccups....just goes with the territory. |
