53cc 4 Stroke Square Key

[Nikoliki]

The rear transmission gear looks like it has bent the square key. Does anyone know what size the key is?

This is an ebay china doll kit not a grubee.

I'm asking before I pull it off. I'm waiting till tomorrow to get my free bucket from HF to buy a pulley

How much time is on that? I think I have a similar set up but haven't run it yet. I'll have to watch out.
