73. CARBURETOR BOWL CLEANING.
a. Water from fuel, water moisture, and dirt entering air cleaner will settle in bottom of carburetor bowl and will interfere with engine starting and carburetion. At periodic intervals bowl must be drained. NOTE: Before draining and flushing bowl, clean fuel strainer (par. [72]).
(1) Support vehicle on jiffy (side) stand.
(2) Shut off fuel supply valve.
(3) Remove bowl drain screw. Let fuel, water, and dirt run out of bowl. With drain screw still removed, open fuel supply valve (turn to left) and leave open only a few seconds, to allow fresh gasoline to flush out bowl.
(4) Replace bowl drain screw, taking care to avoid thread crossing. Set screw snug, but not tight enough to strip the threads.
