The Kester solder Mouser part nos. are different in present Mouser catalog. However, by inspection of the numbers which are similar I can tell you that nos. containing 6040 are 60/ 40 solder.
Nos. suffixed with 88xx seem to all be "NO Clean" type, which you do NOT want to use! Most likely you have type "245" solder, No Clean, any number on container like 245? Go to an electronics or electrical wholesale distributor or order on line the correct type. One of the best solders in the world for Elecraft or any kit/ or home building is Multicore. It is a multiple core rosin type solder. The company is a division of Permatex gasket compound manufacturer now, but has been in electronics since 1960 or so. My Field Test K2 was built with Multicore solder, (formerly Ersin Multicore of England).
