Yes, I'd say it ought to be a gearing issue at this point. Unlikely to be the housing.
The worm gear wasn't too keen on coming off, so I held it in hot water to soften the plastic. Then it popped off fairly easily. I didn't notice any cracks but I'll happily inspect under a magnifier when I re-open it (I do have a lighted one)
If I get another C12 that runs nicely I'll swap some parts around to try and narrow the issue... or break the pair of them!
