check spark with test light good
New carb

Starts first pull when cold
New spring for auto choke

Can't figure it out any help would be great

after the mower has ran and is hot, remove the airfilter cover and airfilter, look in the carb, is the choke valve open or closed?

Open

Removed the auto choke and carb added primer bulb and different carb starts every time

Hey, that's one way to fix it!
