It looks great!
I'm also trying to build this engine but I can't get it run yet. I think it leaks in the valve. Did you have any problem to get it run?

good morning
no I did not have too much problem .I removed the seal segment because too much friction.
mounting grease the valve shaft because risk of seizure, also use a little oil in gasoline
