What effect does cutting the spring have? Cutting 1 1/2 coils was part of the "carb fix-it recipe" for my KTM LC4. That thing rocked afterwards.
Well, it's a mixed bag. It lowers the preload on the spring, but the spring rate goes up, although it should be more open for any given amount of throttle with less preload.
The stock CV carb is fussy, you might do it and it works great, or it might suck.
