I will say I have a Poulan, and a Stihl, that BOTH go at like half throttle when you use the choke on a cold start. I would NOT put my testicles anywhere near it. You Have to squeeze the trigger once then it will go back to an idle and the chain doesn’t “free spin” anymore.
I’ve also seen a loose chain pick up enough momentum that it cut right through my coworker’s chaps. This is why you should always put the brake on if it’s running but you’re not actively cutting.
It’s funny as shit watching someone have to clean the remains of their chaps outta the chain, and clutch though.
