AFAIK, none of my Cox reedies have this.
You won't need this in a pusher configuration at first. Just check that the crankshaft can not be pushed into the reed assembly, and supply said washer before it does. It may have to wear some before you can even get a washer in there. And that may take many hours of running.
It probably isn't worth the effort. You can toss the engine and replace it for seven bucks.
Just my opinion. Your choice.
