Im doing a 365 spcl closed port and there are still 2 specks of aluminum smaller than the periods and commas on this page, they are below the ex port and just below ring travel, I have been rubbing on these quite a while, do these absolutely have to go? Somebody, please my fingers are getting sore.

Run it like you stole it!
 
CristiRo (and everyone else) Be sure to remove that decompression valve and remove the spark plug,
then carefully clean flush out ALL of the remaining residue from cleaning the cylinder.

The cleaning pad will leave some (abrasive) grit behind, trapped in the crevices of the the decomp valve.
This will also be in and around the threads of the spark plug and the decomp valve.

We wouldn't want to run the engine with that gunk still in the cylinder.
That would negate all of our work when it scarred the cylinder and piston.

That's what I just did. ;)
I also had to clean de carbon build up in the combustion chamber, so the decomp valve and sparg plug had to be taken out.
All the best!
