The problem isn't the gasket between the cover and the cylinder head, it's the seal under the tube nut. I still think that the tube nut should fit tightly in the seal, but all the seals I have bought recently are loose. So far filling the gap with an O-ring seems to help.

Is that a B series 1500 engine?

The handles in the image I posted earlier were made for me by a neighbour with a CNC router fitted with a 4th rotary axis, I provided the ash blanks and the 3D models of the handles. I like an elliptical handle for comfort and indexing but the eye needs to be round as round holes are easy to make in the head. On a rotary knife lathe which would normally be used to make handles the elliptical handl...
