I remember reading on here a while back about somthing concerning a ram funnel type setup on the inlet side of a carburator. Someone was quoting info from "The Two-Stroke Tuning Handbook" and said that a bell, stack, or whatever you want to call it, should flare out to four times the area of the carb in so and so distance. I want these numbers and facts! I know, I could order the book... but I figured this might be quicker (and I just got Solidworks on my P.C. and want to make something that works well as my first part at home!)
