I have an older Ryan weedeater that was given to me and it runs great. The model # on the engine says 264-1. I was hoping someone can tell me what size engine this is? I hope to convert it to RC to power a 1/4 scale cub I am building.

I know Ryan was bought out by Ryobi a few years back so I hope the parts for a Ryobi 31cc engine will work. Can some place help me with this.

Thanks
