Couldn't find the part needed. The rest of the saw is in good shape, motor starts and runs very nicely and has plenty of power for it's size so rather than toss it into a corner of the shed I have gone back to the old daze - filled a squeeze bottle with bar oil and giving the bar and chain a squirt now and then while cutting.
One of my early saws was a small McCulloch which had a manual oiler.
