Probably not a butterfly screw, I think they're usually made of brass (?)
Could be plug electrode like you said....
?

Most are steel since you can pick them up with a magnet. The screw wouldn't be that big and would of left a thread pattern in the head

Most likely a lump of gravel that fell in when a plug or air filter was off.
Slight change it could be a little piece of the alternator magnet so worth pulling the flywheel and checking just to be on the safe side.
Alternator magnets rarely fall out when they break up usually they will clump together.
However if one is falling apart then it will take out the stator and even the rectifier.
Remember it is a stump grinder so will be tossing around a lot of debris.

Thanks all, I’m going to pull the inlet manifold and make sure it’s free of debris. Hopefully get to grind my first stump soon.
