Default Early Blackstone Portable

This engine was brought into my shed for me to do some work on it. It is believed to be the second oldest Blackstone in NZ and dates around 1903/4.It has a forged crankshaft , counter weights in the hub and an atmospheric inlet valve.

It belongs to the Plains Museum in Ashburton 75 kms north of where I live. They have owned it for a very long time. I don't know much about it But I remember it running when we took engines to their open days back in the 1970's.

Over the years it has gone for quite long periods with out being run and it was after one of those periods it was taken to a crankup about three years ago where I got running again. It is testament as to how good these engines are when over the last 50 years it has had very little maintenance. The engine is in very good order and has great compression and very little mechanical noise.

I made and fitted a new hotbulb gasket and freed up the 'timing' valve. The hotbulb cover was all rusted together and required some encouragement with the oxy torch to get it all apart, surprisingly the nuts holding the hot bulb were only finger tight and came off easily. I had to do a little work to the oiler to get the flow consistent.

It will be going back this week and will be at a crankup next Saturday, so all that is required now is a good clean up.

Here is a video and pics.

John, the number is 39794, I don't know if it has been dated officially, but I was told it is 1903 which I suspect is not far away.
