Alan,
I am trying to determine two things as follows:
1. I would like to have a basic understanding of what the affect of changing
carb spring rates has on an engine if no other component is changed. Kind of
like changing needles, of which I have a basic understanding.
2. I have a BJ8 engine with 10:1 compression, a 272 degree Elgin cam and
triple HS6 carbs. There is no factory spec for this set-up. So I am interested
in knowing what I might expect if I were to make a change to the springs.

The only way to "retune" a carb that has a different than spec spring is to
change the needle accordingly, otherwise the carbs will be out of balance
regardless of the state of balance at idle. Your carbs must have matched
springs. Just buy a new pai, they aren't expensive.

Is a red carb piston spring stronger or weaker than a green spring?
Also, if the only thing changed is the spring, for instance red to green, I
assume the carbs would have to be re-tuned. Once the carbs are re-tuned what
would be the affect of such a change?
