I noticed that in the Lycoming SI #1443F the magneto's listed for my engine are both the same. Listed is the Slick 4371. The 4371 has the impulse coupling, I believe. Why put two impulse coupling mags on one engine??? I currently have older slick mags and only the left side has the impulse coupling. My engine is the AEIO-320-E2B.
