G'day Jaffa, pleased your mower work out alright.
First time I have ever seen that style of carburettor, so I looked it up.
Here is a great thread for servicing it.

All the Techumseh engines I have done so far, have worked out really well, except for the one I am doing now. I have tried 3 different carbys now and none of them prime the engine for starting. Once the engine is running, it is fine.
So will have to buy a new carb to complete this mower.

Happy is he who penetrates the mystery of things.
