In case anyone is interested, there is an NOS HIRO engine on the Asheville, NC Craigslist. (http://asheville.craigslist.org/mcy/1383363954.html) I don't know the seller or anything about the engine. My son saw it and thought a POG member might be interested.

Thanks Nelson...I originally listed my HIRO engine on the POG site but there was no interest so I've expanded my audience to include the Craigs List forum. I've since lowered my price to $1495 from my original posting.
Anyone interested may call me at 828-551-0311 evenings.
