I misspoke in that when I replaced the grip and throttle cable I also replaced the brake lever unit which is a casting that has the "stop engine" i.e. decompression lever attached to it. The new brake lever unit didn't come with the stop engine lever and I would like to reuse my old one. But I can not remove it from the original unit. It looks like it just snaps in place, but I don't want to apply too much presser for fear of braking it.
I attempted to attach a pic, but it is over the maxim size allowed.
