All the saw I worked on are choke out and trigger to set high idle, just when you get to that point changes.
Sounds like the 590 and 620 are similar, based on the same design at least.
If you try to pull too many times with choke on, just floods.
Putting the brake on is for safety during starts, especially ones off the ground (drop starts etc.)
Never start by holding the trigger, most saws will flood pretty quick.
Husky, Jonsered etc. are similar choke systems. But as with everything, some saws are slightly different and some completely different. toggle switch or momentary contact for power on.
Points (on much older saws) or electronic spark. Chokes that connect to start switch vs. separate.
Some have purge bulbs, some don't, some big saws have decompression buttons, some have spring assist.
I buy from a shop and he starts the saws and makes sure they are setup. Then I ask him what I will do wrong first with starting it, and he shows me
