One of the problems with the Monro Tiller and other machines with a similar chain drive to the rotors is the bottom wears out, this might explain the wooden case.
Hi Charlie,
I’ve been waying up the rebuild and on looking at the parts list can not find a gasket between the gear cases and I must admit when I took it apart did not find a lot of material . Did they just use sealer ? I have made a new gasket but are scratching my head now.
