I have that spineer on OS 65AX, and hole in the backplate of that spinner in bigger.
No worries, you just have to center the backplate, otherwise spinner will wobble around.
I used narrow masking tape, and i carefuly made couple of turns around the shaft, so backplate fitted in snuggly.
Oh, and I had to order new brass nut, becouse my engine has M8 thread on shaft, and that prop adapter that comes with spinner has M6 thread.
Without that nut, you can't fit spinner on backplate.
Yes, you can fit it on glow engine, you just dont use that prop adapter that comes with the spinner, and you may have to order new top nut. That nut that comes with spinner has M6 thread on one side and M4 thread on the other. I had to order new brass nut that has M8 thread on one side (so it would fit the shaft on my engine) and M4 thread on the other.
It turned out to have a 3.175mm shaft.
Fortunately the spinner base takes a standard shaft adapter.
Can take up to about a 14x8 prop.
