Great job and nice engine, i hope mine works like yours ...Awesome work!! got mine running again after the valve job.
Runs better then ever.Cant´wait to see yours running.
I did my pump from aluminium and glued the two halves together with jb Weld.
Only a small grey seam is visible.
Have you made the pistons yet? do plan to make oil control rings?
I have some smoking with mine and i just used two compression rings and one grove with holes.
If you allow, I have another question:The pipe is made out of several pieces with different diameter joint by soldering. Then the joints where filed/ground down on the lathe.
The piece is almost cylindrical but looks like conical.
