-"Hi. What order does the mixture assembly go in?

Commonly generally speaking it should be in order: O-ring/shim washer/spring/screw
if O-ring is Against spring, the turning spring will eat scrape damage the O-ring surface, it will mangle it its shape totally...
O-ring will get Swallen from petrol fumes/oil etc , Due it, it O-ring seals properly then against carb body..
on some carb's Generally speaking the Screw bore bottom at carb body also often is Conical shape, not Flat.
Generally speaking on some Applications such Conical shape bottom works as seal against with O-ring(s).
im ex metal worker cnc nc-fanuc machinist, autocad etc Designer. mc-mechanic by ex dailyjob.
so double check if needed, as i didnt look any of my 139qmb CVK's right now, and i forgot among million things going on atm....BUT 99,99 % sure our CVK's are the same, also by Common sense...

That the order I installed it in yesterday. It was only order that would make sense. I just thought I saw it come out that order and it felt like something was wrong. It didnt fix the issue. Something else is wrong with the carb. New one is arriving today

Tortoise,
Thanks for the photo, I’ll add to my collection of all things GY6.
Nitrile O-rings are pretty much impervious to petroleum. They are/were used to keep oil well gasses & fluids out of the electronic logging gear used to evaluate the formation in the well. They’re not rubber.
