I dig through all my stuff. I can't seem to find one of those shims anywhere in four sets of cases with final gears. They all look the same.
However when going through all my shit I realized when I replaced the pedal shaft seal on my clutch cover I put it in backwards and pushed all the way down to the bottom of where it normally sits. I guess I forgot how it was oriented when I went to replace it.
I'm wondering if that has anything to do with my issues now. I don't really see how a seal would cause that especially since the pedal shaft doesn't actually butt up against it or anything. Either way. I've fixed that now. If that was my issues I'm going to to feel really stupid.
Honestly I hope it does but if not I guess the hunt continues for this shim. I was sure I'd have one in my bin full of cases but if I don't find one or find a different solution soon I guess my next step will be ordering that shim from moped junkyard.
