To richen the carburetor:
1. Change the main jet one number at a time (larger).
2. Lower the needle clip (raising the jet needle) one notch at a time until the engine
starts to blubber on the top end, then move the clip back up one notch or until you
get the blubber out.
FUEL MIXTURE SCREW
The smaller brass screw that is towards the front of the engine is a fuel mixture screw.
This screw will also richen and lean your engine more on the bottom and mid-range. In
warmer conditions, turn the screw in. In colder conditions, turn the screw out. Be sure
to keep the carburetor very clean and make sure you don't have water or dirt in the
carburetor bowl. Use automotive carburetor cleaner or WD-40 to clean the carburetor
inside and out.
Cleaning the carburetor:
Clean the carburetor in a well-ventilated area, and take care that there is no spark or
flame anywhere near the working area; this includes any appliance with a pilot light.

point solvent to clean the carburetor.
1. Make sure the fuel is shut off.
2. Remove the carburetor.
3. Drain the fuel from the carburetor.
4. Disassemble the carburetor.
5. Immerse all the metal parts in a carburetor
cleaning solution.
6. After the parts are cleaned, dry them with
compressed air.
7. Blow out the fuel passages with
compressed air.

The motorcycle will only operate properly if the carburetor top is installed properly with
the mounting screws, cable and choke knob oriented as shown.
