I converted one of those engines. I got it out of the Homelite 14" chainsaw, called the "Bandit" I think. It's a great engine! It already has the bigger carb and has better compression than the stock Homie 25s. I have it in my BUSA Fokker DR1 and it hauls it around great. I'm using an 18-6 prop but I'm sure it can handle more. I wish I had known about these engines before I got my 25s. They are less work to convert. You just have to make up some kind of beam type firewall mount.
