We got a Suzuki Snowblower made in the seventies with a snowmobile engine on it. It is called sr20 It says sm20 on the engine. It only has one cylinder with a block off plate on the other cylinder. I need a carb float for it. It is a Mikuni clamp on style with a governor. Help!!! This thing is so cool and it's mint. It runs but the float doesn't float-it has a hole in it and one is collasped.
