Make sure that the bearings and the hubstacks and the O-Ring is in it’s place and nice and tight. And it should be OK. ---

It’s probably because he put to much pressure on the hubstack and now it vibes and wobbles when he pull starts it. Just make sure everything is tight and in it’s right place. ---

I Had a similar problem when I got mine you may want to see if bearing is jammed. Remove the stack check to make sure the bearing spins freely. If it still has a vibe try sanding the inside of the stack (Just a little bit). Can’t explain why that works, but sometimes it does. ---

Define tight. If it’s tight like the stack won’t come off you may need to use pliers to get the stack off. ---

You can pull it off if you really pulled hard. But it’s best just to use pliers. ---
