I actually used some spring caps (that push the rollers) from the spare Honda 150 I have. They were exactly the same and from the picture above you can see that I needed a new set! I highly recommend buying a broke ol Honda parts bike to rob engine parts from and spare nuts and bolts. A ton of the old Honda 60 bikes use the same parts here and there. And to show people exactly what is inside the starter clutch. I have a couple extra parts laying around in this photo but you can see that there is a HUGE potential to lose parts when you take this assembly apart. Don't lose anything cause you ain't going to find any of it at your local hardware store!!!
Here is a pic of the spankin new starter assembly as I was ready to put them in. I've been waiting to put these parts back in for over 10 years!!
