If the engine has been somewhat maintained, it shouldn't need a chain. I have only replaced two in ten years of working on these engines.
I would allow for 5-8 degrees of stretch on this one, but you will not find that much.
(8 degrees is only 2.5% of crank rotation. ON a gas engine, that is nothing)
