Very impressive stuff! It's made me revisit my TEEoPA engine with a view to sprucing it up a bit.
You stated, "Fuel cell cover has domed wick holder with no cylindrical extension, held in place by circular lock washer with inside "fingers" to act as clamp." I wonder if you have a picture of the fuel cell. My engine came without one, so I got a chromed faucet plug to fit the recess, but I don't know what goes under the plug.
