On this particular one, there is either nothing holding it in or I broke the pin already. I didn't see the pin fall out and a print of the clutch assembly didn't show anything holding it in so, it's very possible, since it has to be turned quit a bit for it to unlock, that's all there is to it. Actually when I think about it, there was no hole for a pin, just a groove somewhere around the center of the rod.
At any rate, got it out, moved over and back on, but there was no way I could really tell till it was out of the way that the cover is now in the way. I can either take some off the cover or try to extend the pipe...it only needs about a half inch. Most likely, if I fit it well, a hose clamp and a piece if rubber tire tube will seal it, but I'm looking into trying to solder it now. It will entail aluminum pipe which I have that fits into the carb nicely and the, what appears to be the chrome plated manifold.
I get by but I'm no pro on soldering, but see on youtube this can likely be done with aluminum brazing rod and a torch. I haven't looked into it enough to find if I could just do it with standard solder/flux...do you think that is possible? I'll go look closely and see what my best bet is..grinding, or adding to the length of the manifold.
