Good result here. I find a lot of these machines where the valves are closed up and if they are really bad like yours they eventually flog out the starter which makes things difficult unless you have another chonda starter to fit.
In the last week I have had a Sanli and a Gardeners Choice Chonda's with exactly the same problem as your Scott Bonnar.
I adjust them at inlet - .15mm and exhaust .20mm and I haven't had an issue yet. When these machines are well serviced they are always 1 pull starters.
I too like Donnyboys video's. He is a very good teacher.
Anyhow good work.
