Justin, Hi. Just a thought you might want to check. You didn't say what might have caused the engine to stick, so I'm just giving you a bit of my experience.
I have a little C that was running just fine (I thought) till it surged a couple of times, stopped in her tracks, and wouldn't turn over for love'ner'money!
The fellas on the forum were fantastic, and I surmised that at least part of the problem was governor associated. Imagine my surprise when I decided that it would be a good time to have the starter overhauled while it was down and I was contemplating a major overhaul, that when I went to pull the starter, the starter drive was still engaged in the flywheel!! Soon as I pulled the starter out, the motor was free as a bird!!! The last time I had started her up, she was hard to start, but that was when the drive "stuck" and was driven by the flywheel till the starter motor seized tight, locking everything up. Fortunately I did no damage to the ring gear. I did replace a well-worn governor and things are hummin' again.
So you might want to at least consider this possibility.
