How do I know if my Continental O200 engine
is set up for a pull-type starter or a factory key-start type
Refer to this drawing extracted from the
Illustrated Parts Manual for Continental C-85 through O-300-C
See how parts 19 and 19A/19B can be
Using part 19 sets the engine up for use
with a pull-type starter (cut part 19 flush with case to use
Sky-Tec C12ST2/S starter as part of KCST2 STC conversion kit).
But for factory key start aircraft - Late model
C150's/C172's, etc.- set-up with a factory firewall contactor
(solenoid) and mag switch that has "START"
position, (what we simply refer to as "key start
engine"), set up your O200 with Part(s) 19A/19B so you
can use either the stock Continental key-type starter, or the Sky-Tec C12ST2.
A) If your engine is set-up with part 19,
cut part 19 shaft flush with the rear of the crank case per STC # SE10076SC
and order/install Sky-Tec P/N KCST2
(which includes starter C12ST2/S and
the KCSW switch/placard kit required by STC
B) If your engine is set-up with part(s)
19A/19B, order/install starter C12ST2.
No STC is required for this installation as
it is PMA certified via PMA
PQ0852SW Supplement 5 as a replacement
part for the factory key start starter(s).
