Hi guys
My cousin is working on a ruby 1937 for a friend. He had it running well. Then the next day fired it up and it was terrible. On investigation the valves were all varnished and sticking. He de coked and replaced all the valve springs. Noting there was a bit of play in the pistons. After this it was running like a sewing machine. So he returned it.(10mins drive). The owner started it up. Drove 10 meters and it conked out.
The valves are all varnished again and sticking.
Any idea what would cause this ?
Sugar in the oil!!??
