Ariens used a jackshafted reverser on the later rockets there was a clever way they got the reverse back, if i can find it i will post a picture. Then you can use a 6 hp predator from HF. I have been repowering Horse tillers with O issues. Those engines will run circles around the old obsolete kohlers and tecumsehs. That is a sad sad fact. Nothing available for either mfg engines any more. All parts easy to get and dirt cheap for the predator.
