Carb is an older 950hp on a 383 with a 496 stoker kit. Motor shouldn't really matter, this is more of a generic question. What's happening is when at cruise, about 2500 rpm, I've got the air fuel ratio in the high 13s', set by adjusting the main jets. But when I accelerate slightly, like going up a hill, it leans out to 15/16. Not hard enough acceleration to open the power valve, but lean enough to feel it surge. I was wondering what increasing the size of the jets and the air bleeds at the same time would do. If this would help maintain the air fuel ratio where I want it? Any ideas, suggestions?
