Thanks ! I think the wobble is a camera / vibration thing. This wheel is the one I fixed properly by drilling the set screw locations. I'm now in the process of removing the other one, which has worked itself loose and fix that one accordingly.

I will do all wheels / gears like this. Just a set screw on a shaft is not cutting it on hit & miss engines. Every time it hits it
gets a punch. Of course they rotate over the set screw.....

This is my general idea until now. Nice engine, beautiful piece of work, but needs lots of improvements on sturdiness of construction.

And this is part of the fun, right ?
