Can anyone help me here, I have been converting and flying Ryobi's for about 18 months. So far these conversions have all been single ring 28's and 31's and one twin ring. Reciently i aquired 3 cross flow moters, one out of an old Ryobi weed basher and 2 from McCullock blower vac's. All are the same in that they have a practicly identicle crank case assembly to the Ryobi but the barrel is cross flow and bolts down wth 4 bolts instead of two. The magnito has cooling fins on both sides.
There are no identifying marks, numbers or brand on them, would anyone know what make they are. Would help when comes to bying parts me thinks.
