Good lord it all goes wrong together

So i went out mowing after work. Well my new troy built hedge trimmer starts perfect but as soon as you hit throttle it dies. It is a 4 stroke.

My deere z425 will not stripe at all even with a homemade stripper behind it. Went to a friends place mowed half his lawn with mine at 4 inches then the rest with his super z and no stripping kit. I stripe like a champ with his and nothing at all with mine.

My proline will also not stripe at all and 3 out of 4 yards the stupid brand new deck belt...
