I have found the plastic bush that came from the bottom of the crankcase.Or maybe the remains, I don't know as what it should look like. Now as you can see it seems to have a lump on one side.Now I don't think it has melted that way by the look of it,it was made that way. In fact I would suspect that it should go all the way around to hold it in place better. Now here is the bush sitting in where it is suppose to go,but as you can see it doesn't fit properly.I know this may not help in finding a replacement. I just wanted to show roughly what it is I'm looking for.
