Unless the engine was apart before and not reassembled correctly, there really is nothing to get stuck. And on this engine, it would be difficult to mess up unless one is really not paying attention.
At least you are making the attempt and learning, give yourself credit for that.Since my last post, I did a little more inspection and I found........... OK, once I type this feel free to call me an idiot.... The carb throttle shaft does appear to be tight and not easy to move. I'll look into this more tomorrow.
You know, I even had the carb apart this summer, cleaned it and never noticed it. Maybe it seized up a bit sitting and not being used for the last month.... but I suspect not.
Anyway, embarassing as thist is, I will come back and finalize this thread once I have confirmed things and all is working again.
ps: Yes, I can't see any part of that governor sticking except for damage... which I didn't find. A lot of needless work, but oh well; it needed an oil change anyway.
