Observe the numbers stamped on each jet, which will be a 50 or a 51, depending on your local elevation. With multi-carbs, that number may be 45 or 46. Experiment in replacing those jets with larger or smaller jets to increase or decrease your fuel/air ratio.
so can i assume that that larger the number the richer the mixture? i'm afraid i know nothing about performance modifications like multiple carbs, etc.
