If it is necessary to remove the carburetor from the engine, remove engine trim as needed, then the air filter cover and air filter. Slide the breather tube (the lower tube in #1) off the rear of the air cleaner base.
Remove three screws (#2) from the air cleaner base and remove the base. Pinch off the fuel line to stop fuel flow and remove the fuel line from the carb.
#3 shows the back side of the air cleaner base and the gasket between it and the carb. This gasket usually gets damaged during Disassembly, Cleaning and Repair and is critical, especially for applications that use a primer.
Disconnect the throttle spring from the control lever (#4).
Remove the two carburetor mounting screws, and slip the carb off the dog-leg end of the throttle rod, lifting the rod up and left, and rotating the carb counter-clockwise (#5).
The above photo (#6) shows the position of the screws that were removed. It also shows the O-ring fitted to the intake pipe.
Check that the plastic intake pipe (#7) is secure and not cracked or broken, especially if the carb or its mounting screws were found to be loose.
#8 shows another view of the intake pipe, with the carb in place, and the throttle rod and throttle spring.
#9 and #10 show additional views of the choke and throttle linkages.
