Install appropriate propeller and tighten securely.
To facilitate electric starting, Install an O.S. solid
aluminium alloy spinner-nut for centering the rubber
drive insert of the starter. Alternatively, a good
quality spinner, enclosing the propeller boss, may be
used, but make sure that it is of precision-made and
sturdy construction so that the spinner shell cannot
loosen when the starter is used. Close the throttle.
