Last time I commented this same thing on this picture someone reminded me that chainsaws often use centripetal clutches so there’s a bunch of ways it can accidentally engage without actually hitting the throttle
A major way is usually the engine runs at higher RPM while choked, so without the brake on, idling with the choke on will likely move the chain with “don’t want it up your crotch” amounts of power.
