Ultra 150 carb springs
I have heard a few people say one of teh things they do for better topend besides milling the heads and adding flame arrestors is to lower the carb spring pressure? Are they talking about the diaphram spring or the neddle and seat spring?

all that does it let the slides come up faster. This can usually be accomplished with drilling a hole in the slide.
I spent many a day on bikes carbs and I'll tell you this. Leave them alone if they work. 2 strokes are all the worse.
