No complicated head like piston engines means no need for a belt to drive a complicated head. Rotaries have ports that just constantly feed on air and fuel.

there is a chain but it doesn't time anything, simply drives the oil pump.

the old old 10/12A engines actually did have a tensioner for the oil pump drive chain.

I knew we didn't have a chain for any kind of timing so I knew the seller didn't know anything of rotaries but I wasn't sure if this was motor specific cause he lists it for all motors lol
