Default question

No updates for you as I'm just now embarking on my quest for gas. But, in so doing I've been looking at ZDZ.

They sell two versions of the ZDZ40. Since the 4.8hp you've listed is the rotary valve version, I recommend you specifically mention (rotary valve) next to your RPM numbers for the ZDZ40.


Thanks,
and this is great information.
