Also not a builder, but a former owner of a homebuilt S-1S with an O-360
with a Sky Dynamics exhaust and a Bendix PS5C pressure carb.

The major advantage of the PS5C for me was that it allowed me to prop the
engine by myself. The plane had no electrical, no starter, and weighed 756
pounds empty.

One tip on the pressure carb.: Always leave the mixture control in the rich
position after shutting down. That helps keep the diaphragms wetted,
extending their life.

Kai-
are there any Pitts S-1 (C/S/T/CC) pilots in this group?

If yes, I would like to ask what your experiences are with your engines.
I'm
in the process to start building a S-1S but have not yet decided which
engine I will finaly use.

Choices are (by now):

O-360
IO-360
AEIO-360

I would like to go for the 0-360 and add a oil system according to
Curtis
Pitts original drawings.

I'm not a builder, but I am an owner- of a factory-kit S-1S with an
AEIO-360-B4A. My engine also has a Sky Dynamics tuned exhaust and
cold-air induction system with a swiveling oil pickup. I looked at
O-360-equipped models, but I heard some things about pressure carbs that
made me think twice about choosing to go down that road (the main issue
being diaphragm aging).
So I was all happy with my fuel-injected engine, and six months in I
had a problem with my fuel injector servo. It required essentially a
rebuild of the servo, which kept my baby on the ground for several
weeks. But I still am irrationally, happy not to have an aerobatic
airplane with a pressure carb.
Other than that, I've been very pleased with my engine, and it has been
otherwise trouble-free.
