I'm looking at the Lycoming Parts catalog for my Lycoming O-320-E2A. On page 4-1, it lists 3 magnetos for this model:
MAGNETO, S4LN-20
MAGNETO, IMPULSE COUPLING, S4LN-21
MAGNETO, S4LN-204
The first two are listed as impulse couplings, and I can't find a listing for the last one.
The Slick application guide lists 4373 for the left magneto, and a 4370 or 4373 for the right magneto. That would indicate that the left magneto is impulse coupled, and the right can be impulse or direct drive.
So I'm trying to figure out what to buy.... Looks like the left magneto should be impulse coupled... but can I go either way on the right mag?
Thanks for any help... I'm probably going to convert this to 160HP if that matters...
