take the exaust off and put it in a camp fire in which it will get red hot and all the carbon will burn off. thats the easyest way without having to use massive amounts of sketchy chems

Sure, use a better quality oil and you won't have the problem to start with. To remove the carbon, remove the exhaust and crap it out of the port.

LOL! Hey spell check only works if the word is spelled wrong, not the wrong word. My proof reading skills need improvement even after all these years. :oops: :cry:

Be careful not to scratch the piston and rings when scraping out the port. I have used a plastic pick and it worked fine.

The rounded end of a fairly stiff feeler gauge works well.
If you want to actually get inside the port, buy a cheap set of small files and bend them to your needs.

A set of small round wire brushes chucked into a drill motor works well for an assembled motor. As mentioned before, do not damage the piston or rings but if you just move the piston to BDC you will not have that issue.

so will it be ok if the small pieces of carbon fall inside the cylinder on the piston?

Yes, or you can stuff a rag into the cylinder to keep it out.
