OK sorry if this has been answered already, but I have a NIB ZDZ 40 rotary valve engine I would like to use. Is this a good engine for this plane? I have the Pitts Muffler that is tapped for smoke oil so thats why I like this engine/muffler combo.

What if any standoffs and what else to mount this engine properly. Also, does anyone know how this muffler will fit properly with the cowl, etc.

thanks for any info on this particular set up. I still didn't receive the CEII yet but will be here soon. thanks!! The CEII is a beauty!!
