death rattle? - with video

[radrob]

dosent sound to bad to me.
the chain is moving around when you rev it up. clutch??
i am still new.

Here's a thought- if the new muffler is quieter, maybe you just hear the rattle more now.

That makes total sense.

it shouldnt smoke like that and mine doesnt smoke or sound like that.
you either have too much or not enough oil in the gas and your chain looks loose.
and you revving it like that is making it worst.

Sounds exactly like my engine that blew a bottom end conrod bearing.

Buy a new engine as it's not worth repairing it - keep the revs low and use 20:1 oil and fuel ratio

That video was about 20 hours runtime ago and it's still running. After tightening all the bolts and adjusting the chain, no more noise.
