You can change the needle settings by the part that is screwed on top of the carb, right next to the fuel line, there is a metal circle thing on top of the carb, unscrew it with a 13-15 mm wrench, cant tell which, and then pull it out, then push the gold needle in and flip it over until the stuff comes out, but rememeber which way it came out so you can install it later....then after that, you move up and down, If you want lean, go to the point nearest to the tip of the needle, if you want rich, go to the bottom.....and then install everything again, you can buy a jetpack from scooterparts4less.com
