My older brother sent these my way from a clean out he did. Don't know much other than the PO was a bit of a mad scientist and said they both ran. The 444 has had a military twin swapped in. It appeals to me in a mad scientist kinda way. Has a foot throttle. The 446 has a Onan twin. Should be a fun weekend getting to know them. Probably do a bit of work to the 446 and find it a new home. The 444 I'll probably just have some fun with it!
