The 3 HP LightTwin flywheel had some changes from year to year in the 1950’s -1960’s. You need the right one or your recoil starter will not match up. Post a wanted ad in the classifieds, and put in the year, model number and equivalent model for a Johnson of the same year. I’ve got a couple parts motors around that might have the one you are looking for, but I can’t get to them in the winter. I have one flywheel I think I can get to. I’ll look tomorrow. If I find it, I’ll take a pic and send you a private message. I can’t check the model number because most of the rest of that motor is on top of my flagpole. I think it’s a 1954 or 1955 Johnson if I remember right. I removed the flywheel to make it lighter.
If you have a photo of it before it broke, that would help.
