CARBURETOR — Major Service Operation

The perfectly adjusted carburetor delivers the proper fuel and air ratios at all speeds for the particular engine for which it was designed. The carburetor should be maintained in its original condition and will continue to deliver the proper ratios. To maintain accurate carbureting through passages and discharge holes, extreme care must be taken in cleaning. Use only carburetor solvent and compressed air to clean all passages and discharge holes. Never use wire or other pointed instrument to clean or carburetor calibration will be affected.

Remove carburetor from engine, taking sufficient care to the following:

Dirt, gum, water or carbon contamination in or on exterior moving parts of a carburetor often results in unsatisfactory performance. For this reason, efficient carbureting depends upon careful cleaning and inspection while servicing. Before assembling and installing the carburetor, blow all passages and castings with compressed air and blow off all parts until dry.

When replacing fuel cut solenoid, throttle valve switch, automatic choke heater (choke chamber assembly) idle-up solenoid, accelerator pump control solenoid or air-fuel ratio solenoid, it will be necessary to disassemble carburetor harness connector.
