On the O-470 the starter is always engaged, and a coil
spring clutch acts as a one-way drive . What would the new drive
adapter have that's different?
We put a Lamar starter on an O-470, and it was so gutless
that we ended up buying another old Prestolite to replace it. Those
permanent magnets are only so powerful. I think the Skytecs or
Magnaflites might be better; we use Magnaflites on three 172s and they
work OK.

The starter adapter is always engaged; the starter only turns when
energized, which in turn causes the coil spring clutch to clamp onto the
starter adapter shaft and turn the engine. I think the problem comes from
the lightweight starter (planetary drive gear) not stopping quickly after
being de-energized which causes the spring to stay clamped and causes wear.
