Sure can! Rotor is a 166-0767 and the module is a 166-0785. Have you done the module test in the manual?

I sure could use some info on the onans if  I took the module and rotor from a running 16hp onan engine would it work in the 20hp onan? Thanks for any info in advance! budman2

Great! Thanks for the info!!!!!!!!!!!!budman2             Now I have another choice to make about my 520, the 416-8 speed that I bought is so nice that I don't want to remove the modual and rotor from it!   so I still need the modual & rotor for the 20hp onan!  Guess I'll have to fork out the $ for a modual & rotor anyway!
