I think the loading on the eccentric shaft is "better" with the 132 firing order.

I think the harmonics is also not as bad.

3 20B's and all have the 1-2-3 firing order based on rotor position.



Anyone out there with a 1-3-2 20B?



Anyone have any solid info on this firing order deal?

Roger Mandeville said 1-2-3, but you could run it 1-3-2. That threw me for a loop so I stopped asking questions :p
