Might need to run it rich to flush that out those are metal fragments ... They need to be flushed out! Does it still have pinch at TDC ? flip it over with the GP out and spray WD in it and flush it!!!! Its probably not bad .. it happens!

That would bother me enough to at least get that stuff out

Is there fuel washing out the pipe?

Whats happening is the parts are fitting and its rubbing off any metal in its way for a good fit !!!!!

You should be good! just keep flushing it if you notice it!

It looses alot of power so If you have lost it its time for a rebuild or replacement
But if it fires and runs strong dont bother with it yet!!
