If I had to make a video guess,I would hope it's just a mixture problem.
That sounds like a lean knock to me, clean your carb ,check the needle is in the right position (clip/groove) turn your mixture screw to try and 'richen' things up..
I hope it's that simple.
There are two types of men in this world:-
1) Those who are Geordies and..
2) Those that want to be.

my gas gas 300 seems to make a knock noise when letting off the throttle, ive tried to video it but it sonds abit tinny on the video, it sounds abit like the piston slapping... ive heard about pinking and wondered if it was this? any ideas how to cure it?
You may have a stock #35 pilot, try changing to a #38 before engine work.
