I need some jet help...  By  bigtzzy (Read 440 times)

www.scooterfocus.com/scooter_carburetor_rejetting.html On most carburetors, the main jet is the one which sticks out as shown above. The jet itself is actually just the top part of the brass tube which sticks up out of the aluminum carburetor body. The lower part is the atomizer and it can stay in the carburetor body. Only the main jet needs to be changed. Be sure to use the right size screwdriver to remove it. Brass is quite soft and you don't want to damage the screw slot. So unscrew the main jet (you might need a wrench on the atomizer tube) and replace it with the new one. Screw it in tight, but you don't need to use a lot of force. Just make sure it's not loose.
