Anywhere you want to...most install it on the handlebar. When the engine is COLD you may need some choke (restricting air flow through the carburetor), Rotate the lever counter clockwise (about 1/2 way to start), then when the engine is warmed up, rotate the lever fully clockwise (no choke).
Truthfully....With your little knowledge of a carburetor, it most likely be best for you to purchase a NT or a NT speed, and sell your CNS to cover your expanses. I have over 50 years experience (can't tell how many I've rebuilt) with carburetors, and I wouldn't want to fool with a CNS, when a NT works fine.
