KD3s are great runners, when they are right. You don’t NEED to pull the tank to pull the flywheel; but doing so will make your life 10 times easier. There is a fairly recent thread here, about making a modern and readily available impeller fit into these motors. Gear case seals are usually shot. use John Deere cornhead grease or equivalent. Parts lists with pictures are a little hard to come by but I think somebody here has one. If you know how to start a 3hp OMC product, then you know how to start a KD3. 16:1 fuel/oil ratio. They have plain bearings, not rollers.
Long live American manufacturing!
