Q: Does S4LN-20 have impulse coupling? I thought only S4LN-21 had that.

You are correct, only S4LN-21 has an impulse coupling. S4LN-20 does not.

Q: Are these priced and sold is for each magneto?

Yes, these are new units priced as each.

Q: you say 20 is RH and 21 is LH. does it mean right and left handed? but the rotation (L) is same on both, correct?

Both mags are LEFT rotation, LH and RH are referring to which side of the engine they are installed.

Q: Does the -21 come with an overhauled or new impulse coupling? As in, is the impulse coupling part of the exchange price?

This mag is not impluse coupled so one is not included. The impluse coupling is included with IC mags though.
