Hi guys and thanks for the reply.

It is definitely a mk2 As it is belt drive and has the metal front roller. I believe it has a 4 stroke engine fitted to it and it is the original.

Engine siezed on me today. All I really want is something to replace the old engine with something that is suitable for the machine whether it be new or used.

I was hoping that it was going to last longer than it did but it is a really old machine and the engine was tired. I know it is probably easy to fix if I were to pull it apart but in the short term I just need it working over summer so I can keep my lawn looking good.

The local mower shop told me to scrap it but its tooooo good for that.
