Adding a starter is a trivial chore but on a properly assembled engine
there is no need to do so unless the engine is mounted on a pylon,
geared, or the prop is otherwise remove from easy access. With a
suitable ignition system the engine starts as easily as a lawn-mower
and will continue to run so long as their is fuel and air, unless it
is shut off..

Some conversions, such as the Aero-vee, use an ignition system having
a single, fixed firing point. The engine will not start unless
rotated at about 300rpm, making a starter motor a necessity. Others
use a belted or geared drive having such a high ratio that hand-
propping is impractical..

When all elements of an electrical starting system are included, the
weight can be as much as forty pounds more than for a hand-propped
engine.
