So i just finished cleaning up the intake and exhaust ports, as well as polishing the exhaust port on my 80cc metrakit. I blew it out with compressed air and then cleaned it with gas. I then put some 2 stroke oil on it to prevent rust. I cleaned it pretty good, but when i was putting the oil on it, i felt a couple pieces of metal dust. Will such a minimal amount of very fine dust cause problems or no?
