Nice job the the "Vickie" Jack. Its a beautiful engine and yours is running very well from what I see in the video. Do you find it is rather stiff when totally cool and takes a while to heat up and run once you apply the heat to it. Mine has been that way from the beginning, but once it's warmed up it runs like a sewing machine. There is a lot of metal there to act as a heat sink for sure.
Again, well done.
