"Ball" hone..
Use a "ball" type hone,(looks like dingleberries on a bottle brush!)--its easier for a novice to use,and removes less metal than the usual 3 stone type hones...it probably will only take a few seconds to remove the rust...use diesel fuel as a lubricant while honing..
Use HOT water and liquid dishwashing soap to clean the metal powder out of the cylinders,and block!---DONT use gas or solvents like brake-cleen,it'll just make it sink into the pores of the metal,and it'll ruin the rings and pistons faster than you can say"whoops",fisrt time you fire it up!--SOAP AND WATER is the ONLY thing that removes it all!..when you can wipe the cylinder with a clean white terrycloth towel,and it comes out with no black residue,its completely clean!...
I use wheel bearing grease or STP on freshly honed engines I can't put together right away,but some of them rusted anyway,UNDER the grease!.

--it helps to have a insulated/heated shop,mine isn't,and things "sweat" in there..
