My Coleman Powermate 5000 / 6250 Peak Watts with a Tecumseh 10 HP HM-100 engine had plenty of metal specks in the first oil change, and some in the second oil change.
My Generac ix2000 not so much.
It is probably mostly about how much time the machine shop that makes the parts that goes into the engine spends on cleaning each part before it is assembled. And there is bound to be some metal from the breaking in of the matching of the moving parts close together like the piston and cylinder.
Just because a machine shop does not clean the parts very well, does not mean that the tolerance and design of the engine is bad.
Your engine is probably better off if you do a few oil changes with low hours to get those metal specks out of there before they cause unwanted wear.
