I had one...getting hard to find parts for, and they are maintenance intensive..stay away if possible. Very heavy engine and very thirsty.

Just curious. What year was these engines, and what kind of power?

they were problematic from new....they dont like to be spun up past 5k RPM and parts no longer exist basically.....

is this part of a package or are you considering buying it to hang on something you already own?
