Motorized Bicycle Carburetor Adjustment - รักษ์ นา โคก ฟาร์ม สเตย์library After reading aussie steve's post about carb tuning i moved the needle adjustment to the leanest point, this helped but i am still running too rich, where do i go from here. There are also (usually) 2 adjustment screws on the exterior of the carburetor. The first (which is usually easier to access and larger in size) is the idle control screw. This screw is responsible. Reinstall the nt carburetor on the bicycle engine and take the bike for a test run.
