Vans YIO-360-M1B Magnetos

quick question, do you know if this engine comes with only one left retard impulse magneto and non Right side?
I'm wiring my ignition switch and need conformation that the ground link is in stalled for the right magneto?

thx

When I purchased my engine last year, there should be at least 1 impulse mag, and you can have a choice on the right side.

Yes, the left side is the is the impulse mag and the right side is the P-Mag.

And technically, when the IO-360 has a left mag and a right P-Mag its not longer a -M1B, its a YIO-360-EXP58

EDIT: I was never given the opportunity to chose which side the P-Mag was on...I definitely would have reversed the set-up I received

Edit Edit: I would have preferred no impulse mag....
