The location of the plunger for raisIng the piston is
here illustrated. The air c\llaner has been removed

To prevent any dust or dirt from entering the piston

from the air cleaner through two holes in the car-
buretter flange and drillings in the body of the car-
buretter.
No damper Is used in earlier units. (See Section
P.5.)
A piston raising pin is fitted at
the right-hand side
