OK Theo, today I started.
Wanted to see how she ran so after cleaning the carb and giving it a primer plate "O" ring and carb to inlet "O" ring. Blowing out the snorkel with compressed air and a new air filter. Put on a donor decompression valve, replaced fuel, decompression and governor tubes. Seeing how it was pumping oil out of the exhaust port, thought a few table spoons of fresh 40-1 fuel, into the cleaned out tank, would do for a short test.............started first pull!

It's difficult to see into the exhaust port, never-mind take a photograph, but I wanted to get some affirmation that what I'm seeing is cross hatch, or rather, machining marks running around the diameter of the bore? Surely not.

Should I take off the carb inlet to inspect the exhaust side of the bore?
Is there supposed to be an exhaust gasket on these?

Because of corrosion will paint the frame and handle with paint I have on hand, won't spend much on it if I don't have to as I will keep it.

It had a Bosch R 10 (?) plug in it, replaced with known good CJ8 for test.
