lever allowing you to remove the
venturi lever from the case.
CAUTION:
Take care not to damage or distort the venturi tab when
removing the venturi lever (24). DO NOT depress the tab of the
venturi lever too far, as this will result in permanent deformation.
NOTE:
There will be some slight resistance removing the two parts
above due to the o-ring (11) underneath the inlet shroud (12).
